UPDATE: 
Finally tableview refreshing is resolved in JavaFX 8u60, which is available for early access.

<hr>

About refreshing see the <a href="https://stackoverflow.com/q/10912690/682495">Updating rows in Tableview</a>. 
And about the blank column see the <a href="https://stackoverflow.com/q/11033404/682495">JavaFx 2 create TableView with single column</a>. Basically it is not a column, i.e. you cannot select the item clicking on this blank column items. It is just a blank area styled like a row.

<hr>

UPDATE: If you are updating the tableView via <code>reseller_table.setItems(data)</code> then you don't need to use <code>SimpleStringProperty</code>. It would be useful if you were updating one row/item only. Here is a working full example of refreshing the table data: 

<pre><code>import java.util.ArrayList;
import java.util.List;
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;

import javafx.stage.Stage;

public class Dddeb extends Application {

 public static class Product {
 private String name;
 private String code;

 public Product(String name, String code) {
 this.name = name;
 this.code = code;
 }

 public String getCode() {
 return code;
 }

 public void setCode(String code) {
 this.code = code;
 }

 public String getName() {
 return name;
 }

 public void setName(String name) {
 this.name = name;
 }
 }

 private TableView&lt;Product&gt; productTable = new TableView&lt;Product&gt;();

 @Override
 public void start(Stage stage) {

 Button refreshBtn = new Button("Refresh table");
 refreshBtn.setOnAction(new EventHandler&lt;ActionEvent&gt;() {
 @Override
 public void handle(ActionEvent arg0) {
 // You can get the new data from DB
 List&lt;Product&gt; newProducts = new ArrayList&lt;Product&gt;();
 newProducts.add(new Product("new product A", "1201"));
 newProducts.add(new Product("new product B", "1202"));
 newProducts.add(new Product("new product C", "1203"));
 newProducts.add(new Product("new product D", "1244"));

 productTable.getItems().clear();
 productTable.getItems().addAll(newProducts);
 //productTable.setItems(FXCollections.observableArrayList(newProducts));
 }
 });

 TableColumn nameCol = new TableColumn("Name");
 nameCol.setMinWidth(100);
 nameCol.setCellValueFactory(new PropertyValueFactory&lt;Product, String&gt;("name"));

 TableColumn codeCol = new TableColumn("Code");
 codeCol.setCellValueFactory(new PropertyValueFactory&lt;Product, String&gt;("code"));

 productTable.getColumns().addAll(nameCol, codeCol);
 productTable.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);

 // You can get the data from DB
 List&lt;Product&gt; products = new ArrayList&lt;Product&gt;();
 products.add(new Product("product A", "0001"));
 products.add(new Product("product B", "0002"));
 products.add(new Product("product C", "0003"));

 //productTable.getItems().addAll(products);
 productTable.setItems(FXCollections.observableArrayList(products));

 final VBox vbox = new VBox();
 vbox.setSpacing(5);
 vbox.getChildren().addAll(productTable, refreshBtn);

 Scene scene = new Scene(new Group());
 ((Group) scene.getRoot()).getChildren().addAll(vbox);
 stage.setScene(scene);
 stage.setWidth(300);
 stage.setHeight(500);
 stage.show();
 }

 public static void main(String[] args) {
 launch(args);
 }
}
</code></pre>

Note that

<pre><code>productTable.setItems(FXCollections.observableArrayList(newProducts));
</code></pre>

and 

<pre><code>productTable.getItems().clear();
productTable.getItems().addAll(newProducts);
</code></pre>

are almost equivalent. So I used the one to fill the table for the first time and other when the table is refreshed. It is for demo purposes only. I have tested the code in JavaFX 2.1. And finally, you can (and should) edit your question to improve it by moving the code pieces in your answer to your question.

I had a similar problem with refreshing. My solution was to restrict the operations on the <code>ObservableList</code> to those which work correctly with <code>bind()</code>.
Assume <code>ObservableList obsList</code> is the underlying list for the <code>TableView</code>.
Then 
<code>obsList.clear()</code> (inherited from <code>java.util.List&lt;&gt;</code>) will not update the <code>TableView</code> correctly but.
Also calling <code>setItem(obsList)</code> did not work to trigger a refresh...but...
<code>obsList.removeAll(obsList)</code> (overwritten by <code>ObservableList</code>) works fine because it fires the changeEvent correctly.
Refilling a list with completely new content then works as follows:
<ul>
<li><code>obsList.removeAll(obsList);</code></li>
<li><code>obsList.add(...); //e.g. in a loop...</code></li>
</ul>
or
<ul>
<li><code>obsList.removeAll(obsList);</code></li>
<li><code>FXCollections.copy(obsList, someSourceList)</code></li>
</ul>

I have an use case where nothing else helped as the solution from Aubin. I adapted the method and changed it by removing and adding an item to the tables' item list as it works in the end only reliable with this hack, the column visible toggle did the job only the first time.

I reported it also in the Jira task:

I had the same problem and after some search this is my workaround. I found that if the columns are removed and then re-added the table is updated.

<pre><code>public static &lt;T,U&gt; void refreshTableView(final TableView&lt;T&gt; tableView, final List&lt;TableColumn&lt;T,U&gt;&gt; columns, final List&lt;T&gt; rows) {

 tableView.getColumns().clear();
 tableView.getColumns().addAll(columns);

 ObservableList&lt;T&gt; list = FXCollections.observableArrayList(rows);
 tableView.setItems(list);
}
</code></pre>

 
Example of usage: 

<pre><code>refreshTableView(myTableView, Arrays.asList(col1, col2, col3), rows);
</code></pre>

The solution by user1236048 is correct, but the key point isn't called out. In your POJO classes used for the table's observable list, you not only have to set getter and setter methods, but a new one called Property. In Oracle's tableview tutorial (<a href="http://docs.oracle.com/javafx/2/ui_controls/table-view.htm" rel="nofollow">http://docs.oracle.com/javafx/2/ui_controls/table-view.htm</a>), they left that key part off!

Here's what the Person class should look like:

<pre><code>public static class Person {

 private final SimpleStringProperty firstName;
 private final SimpleStringProperty lastName;
 private final SimpleStringProperty email;

 private Person(String fName, String lName, String email) {
 this.firstName = new SimpleStringProperty(fName);
 this.lastName = new SimpleStringProperty(lName);
 this.email = new SimpleStringProperty(email);
 }

 public String getFirstName() {
 return firstName.get();
 }

 public void setFirstName(String fName) {
 firstName.set(fName);
 }

 public SimpleStringProperty firstNameProperty(){
 return firstName;
 }

 public String getLastName() {
 return lastName.get();
 }

 public void setLastName(String fName) {
 lastName.set(fName);
 }

 public SimpleStringProperty lastNameProperty(){
 return lastName;
 }

 public String getEmail() {
 return email.get();
 }

 public void setEmail(String fName) {
 email.set(fName);
 }

 public SimpleStringProperty emailProperty(){
 return email;
 }
</code></pre>

}

}|code-block|syntax|javascript|224474|最好在UI更新线程中更新表。但是，它也可以在您更改表中的某些内容后调用updateMyTableView();，因为JavaFX似乎无论如何都会在UI线程中更新(不确定这一点)。|style|CODE|224475|Platform.runLater(new+Runnable()+{

My solution is similar to the the workaround of <a href="https://stackoverflow.com/users/980442/">Daniel De León</a>, but it also works when you need to hide the first column (index 0 in his example). Of course you could just change the index in his solution, but if you are rearranging the columns, my solution might work better for you. The idea is to hide and show the column by its name instead of hiding and showing it by its index: 

<pre><code>private void updateMyTableView() {
 // update table view WORKAROUND !!!
 if (myTableView != null) {
 ObservableList&lt;TableColumn&lt;Entry, ?&gt;&gt; columns = myTableView.getColumns();
 for (TableColumn&lt;Entry, ?&gt; column : columns) {
 // at this point, we look for the specific column, which should
 // always be visible
 // therefore we use the "Column Title" String, e.g. "First name"
 if (column.getText().equals("Column Title")) {
 column.setVisible(false);
 column.setVisible(true);
 }
 }
 }
}
</code></pre>

It's best to update your table in the UI update thread. However, it also works by just calling <code>updateMyTableView();</code> after you've changed something in your table, since JavaFX seem to update in the UI thread anyway (not sure about that).

<pre><code>Platform.runLater(new Runnable() {
 public void run() {
 updateMyTableView();
 }
});
</code></pre>

There seem to be several separate issues around oldItems.equals(newItems)

The first part of <a href="https://javafx-jira.kenai.com/browse/RT-22463" rel="nofollow">RT-22463</a>: tableView won't update even if calling items.clear()

<pre><code>// refresh table 
table.getItems().clear();
table.setItems(listEqualToOld); 
</code></pre>

that's fixed. Clearing out the old items before setting a new list clears out all old state, thus refreshing the table. Any example where this doesn't work might be a regression.

What's still not working is re-setting items without clearing first

<pre><code>// refresh table
table.setItems(listEqualToOld); 
</code></pre>

That's a problem if the table is showing properties that are not involved into an item's equal decision (see example in <a href="https://javafx-jira.kenai.com/browse/RT-22463" rel="nofollow">RT-22463</a> or <a href="http://pastebin.com/QKnvzXTd" rel="nofollow">Aubin's</a>) and covered - hopefully - by <a href="https://javafx-jira.kenai.com/browse/RT-39094" rel="nofollow">RT-39094</a> 

UPDATE: <a href="https://javafx-jira.kenai.com/browse/RT-39094" rel="nofollow">RT-39094</a> the latter is fixed as well, for 8u40! Should bubble up into the ea in a couple of weeks, speculating on u12 or such. 

The technical reason seems to be an equality check in cell's implementation: checking for changes of the item before actually calling updateItem(T, boolean) was introduced to fix performance problems. Reasonable, just to hard-code "change" == old.equals(new) poses problems in some contexts. 

A work-around that's fine for me (no formal testing!) is a custom TableRow which jumps in if identity check is required:

<pre><code>/**
 * Extended TableRow that updates its item if equal but not same.
 * Needs custom skin to update cells on invalidation of the 
 * item property.&lt;p&gt;
 * 
 * Looks ugly, as we have to let super doing its job and then
 * re-check the state. No way to hook anywhere else into super 
 * because all is private. &lt;p&gt;
 * 
 * Super might support a configuration option to check against
 * identity vs. against equality.&lt;p&gt;
 * 
 * Note that this is _not_ formally tested! Any execution paths calling
 * &lt;code&gt;updateItem(int)&lt;/code&gt; other than through 
 * &lt;code&gt;indexedCell.updateIndex(int)&lt;/code&gt; are not handled.

Note that TableCell has a similar hard-coded equality check, so if the custom row doesn't suffice it might be necessary to use a custom TableCell with a similar workaround (haven't run into an example where that's needed, though)

I am not sure if this applies to your situation, but I will post what worked for me.

I change my table view based on queries / searches to a database. For example, a database table contains Patient data. My initial table view in my program contains all Patients. I can then search query for Patients by firstName and lastName. I use the results of this query to repopulate my Observable list. Then I reset the items in the tableview by calling tableview.setItems(observableList):

<pre><code>/**
 * Searches the table for an existing Patient.
 */
@FXML
public void handleSearch() {
 String fname = this.fNameSearch.getText();
 String lname = this.lNameSearch.getText();
 LocalDate bdate = this.bDateSearch.getValue();

 if (this.nameAndDOBSearch(fname, lname, bdate)) {
 this.patientData = this.controller.processNursePatientSearch(fname, lname, bdate);
 } else if (this.birthDateSearch(fname, lname, bdate)) {
 this.patientData = this.controller.processNursePatientSearch(bdate);
 } else if (this.nameSearch(fname, lname, bdate)) {
 this.patientData = this.controller.processNursePatientSearch(fname, lname);
 }

 this.patientTable.setItems(this.patientData);
}
</code></pre>

The if blocks update the ObservableList with the query results.

blocks|key|224531|text|同样的问题，我尝试了一些解决方案，对我来说最好的解决方案如下：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|224532|在控制器的initialize-method中，创建一个空的observableList并将其设置到表中：|224533|obsBericht+=+FXCollections.observableList(new+ArrayList<Bericht>(0));

Same problem here, i tried some solutions and the best for me is following:

In initialize-method of controller, create an empty observableList and set it to the table:

<pre class="lang-java prettyprint-override"><code>obsBericht = FXCollections.observableList(new ArrayList&lt;Bericht&gt;(0));
tblBericht.setItems(obsBericht);
</code></pre>

In your update-method, just use the observableList, clear it and add the refreshed data:

<pre class="lang-java prettyprint-override"><code>obsBericht.clear();
obsBericht.addAll(FXCollections.observableList(DatabaseHelper.getBerichte()));
// tblBericht.setItems(obsBericht);
</code></pre>

It's not necessary to set the items of the table again

經過trace JavaFX 的source code後，並沒有發現bug。利用Listener等方法觀察也沒有異樣。也嘗試利用JFace中的PropertyChangeSupport方式宣告POJO內容變更也沒有效果。最後將DoubleProperty 改為WritableObjectValue，問提就解決了。

Since <code>JavaFX 8u60</code> you can use(assuming <code>tableView</code> is an instance of <a href="https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/TableView.html" rel="noreferrer">TableView</a> class):

<pre><code>tableView.refresh();
</code></pre>

From the documentation:

<blockquote>
 Calling refresh() forces the TableView control to recreate and
 repopulate the cells necessary to populate the visual bounds of the
 control. In other words, this forces the TableView to update what it
 is showing to the user. This is useful in cases where the underlying
 data source has changed in a way that is not observed by the TableView
 itself.

I know that this question is 4 years old but I have the same problem, I tried the solutions from above and didn't worked. I also called refresh() method but still not my expected result. So I post here my solution maybe will help someone.

Even that before of this I used another variable in ObeservableList for setting items into the tableview, I call this a "filthy method" but until I get a better solution is ok.

I have been trying to find a way to refresh the tableView(ScalaFx) for 3-4 hours. Finally I got a answer. I just want to publish my solution because of i wasted already hours. 

-To retrieve the rows from database, i used to declare a method which returns ObservableBuffer.

My JDBC CLASS

<pre><code> //To get all customer details
def getCustomerDetails : ObservableBuffer[Customer] = {

val customerDetails = new ObservableBuffer[Customer]()
 try {

 val resultSet = statement.executeQuery("SELECT * FROM MusteriBilgileri")

 while (resultSet.next()) {

 val musteriId = resultSet.getString("MusteriId")
 val musteriIsmi = resultSet.getString("MusteriIsmi")
 val urununTakildigiTarih = resultSet.getDate("UrununTakildigiTarih").toString
 val bakimTarihi = resultSet.getDate("BakimTarihi").toString
 val urununIsmi = resultSet.getString("UrununIsmi")
 val telNo = resultSet.getString("TelNo")
 val aciklama = resultSet.getString("Aciklama")

 customerDetails += new Customer(musteriId,musteriIsmi,urununTakildigiTarih,bakimTarihi,urununIsmi,telNo,aciklama)

 }
 } catch {
 case e =&gt; e.printStackTrace
 }

 customerDetails
}
</code></pre>

-And I have created a TableView object. 

<pre><code>var table = new TableView[Customer](model.getCustomerDetails)
table.columns += (customerIdColumn,customerNameColumn,productInstallColumn,serviceDateColumn,
 productNameColumn,phoneNoColumn,detailColumn)
</code></pre>

-And Finally i got solution. In the refresh button, i have inserted this code; 

<pre><code>table.setItems(FXCollections.observableArrayList(model.getCustomerDetails.delegate))
</code></pre>

model is the reference of my jdbc connection class

<pre><code>val model = new ScalaJdbcConnectSelect
</code></pre>

This is the scalafx codes but it gives some idea to javafx

JavaFX8

I'm adding new Item by a DialogBox. Here is my code.

<pre><code>ObservableList&lt;Area&gt; area = FXCollections.observableArrayList();
</code></pre>

At initialize() or setApp()

<pre><code>this.areaTable.setItems(getAreaData());
</code></pre>

getAreaData()

<pre><code>private ObservableList&lt;Area&gt; getAreaData() {
 try {
 area = AreaDAO.searchEmployees(); // To inform ObservableList
 return area;
 } catch (ClassNotFoundException | SQLException e) {
 System.out.println("Error: " + e);
 return null;
 }
}
</code></pre>

Add by dialog box.

<pre><code>@FXML
private void handleNewArea() {
 Area tempArea = new Area();
 boolean okClicked = showAreaDialog(tempArea);
 if (okClicked) {
 addNewArea(tempArea);
 this.area.add(tempArea); // To inform ObservableList
 }

}
</code></pre>

<code>Area</code> is an ordinary JavaFX POJO.
Hope this helps someone.

Well after looking for all the possible solutions. Tried clearing data first and then added in tableview <code>tableView.getItems().clear();</code> still that does not resolved my problem. I tried all the answers given here but did not worked for me and I still had stale objects in my table as shown in image below:

<a href="https://i.stack.imgur.com/Nmu11.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Nmu11.png" alt="enter image description here"></a>

In order to fix it I created a DUMMY label and used <code>setGraphic</code> as follows:

}|3091547|因此，在我的controllerA中，我只是用setCellValueFactory装入表，仅此而已。|3091548|entityMap^0|0|5|N|0|0|H|L|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|12|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|13|8|@$D|14|E|15|F|G]]|9|@]|A|$]]|$1|H|3|I|5|J|7|16|8|@]|9|@]|A|$K|L]]|$1|M|3|N|5|6|7|17|8|@$D|18|E|19|F|G]]|9|@]|A|$]]|$1|O|3|P|5|J|7|1A|8|@]|9|@]|A|$K|L]]|$1|Q|3|R|5|6|7|1B|8|@]|9|@]|A|$]]|$1|S|3|T|5|J|7|1C|8|@]|9|@]|A|$K|L]]|$1|U|3|V|5|6|7|1D|8|@]|9|@]|A|$]]|$1|W|3|X|5|J|7|1E|8|@]|9|@]|A|$K|L]]|$1|Y|3|Z|5|6|7|1F|8|@]|9|@]|A|$]]|$1|10|3|-4|5|6|7|1G|8|@]|9|@]|A|$]]]|11|$]]

for refresh my table I do this:

In my ControllerA who named <code>RequisicionesController</code> I do this

<pre class="lang-java prettyprint-override"><code>@FXML public TableView&lt;Requisiciones&gt; reqtable;

public TableView&lt;Requisiciones&gt; getReqtable() {
 return reqtable;
}

public void setReqtable(TableView&lt;Requisiciones&gt; reqtable) {
 this.reqtable = reqtable;
}
</code></pre>

in the FXML loader I get ControllerB who also named <code>RevisionReqController</code> 

<pre class="lang-java prettyprint-override"><code>RevisionReqController updateReq = cargarevisionreq.&lt;RevisionReqController&gt;getController();

RequisicionesController.this.setReqtable(selecciondedatosreq()); 
updateReq.setGetmodeltable(RequisicionesController.this.getReqtable());
</code></pre>

in my ControllerB I do this:

<pre class="lang-java prettyprint-override"><code>public TableView&lt;Requisiciones&gt; getmodeltable; 

public TableView&lt;Requisiciones&gt; getGetmodeltable() {
 return getmodeltable;
}

public void setGetmodeltable(TableView&lt;Requisiciones&gt; getmodeltable) {
 this.getmodeltable = getmodeltable;
}
</code></pre>

then:

<pre class="lang-java prettyprint-override"><code>public void refresh () {
 mybutton.setonMouseClicked(e -&gt; {
 ObservableList&lt;Requisiciones&gt; datostabla = FXCollections.observableArrayList();
 try {
 // rest of code

 String Query= " select..";

 PreparedStatement pss =Conexion.prepareStatement(Query);
 ResultSet rs = pss.executeQuery();
 while(rs.next()) {
 datostabla.add(new Requisiciones(
 // al requisiciones data
 ));
 }
 RevisionReqController.this.getGetmodeltable().getItems().clear();
 RevisionReqController.this.getGetmodeltable().setItems(datostabla);
 } catch(Exception ee) {
 //my message here
 }
}
</code></pre>

so in my controllerA I just load the table with setCellValueFactory , that's its all.

blocks|key|2877695|text|您只需要清空该表，并调用生成表填充的函数。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2877696|2877697|+ButtonRefresh.setOnAction((event)+->+{+tacheTable.getItems().clear()；PopulateTable()；});|blockquote|2877698|2877699|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|J|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|K|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|L|8|@]|9|@]|A|$]]|$1|G|3|-4|5|6|7|M|8|@]|9|@]|A|$]]]|H|$]]

You just need to clear the table and call the function that generates the filling of the table.

I have this common issue, as it appears to be. My table view wont refresh my items after I reset them. I have checked the data and it's the new one. 

I tried multiple solution from internet but no success. 

Can't reset all the columns because it adds one empty one extra (dont know why) and the resize just breakes.

My table is not editable. The new data is changed.

The data is refreshed if I change the ordering of the items and the rows change (:|).

I'm just left without ideas.

At the moment the refresh code is pretty simple.

<pre><code>ObservableList&lt;User&gt; data = FXCollections.observableArrayList(User.getResellers());
reseller_table.setItems(data);
</code></pre>

Again the new data is correct. When I make an selection to the tableView it returns the new correct Item.

我有一个共同的问题，就像它看起来的那样。重置项目后，我的表视图不会刷新它们。我已经检查了数据，这是新的。我尝试了互联网上的多种解决方案，但都没有成功。无法重置所有列，因为它添加了一个空的额外列(不知道为什么)，并且调整大小只是中断。我的表不是editable。新数据已更改。如果我更改了项目的排序，则会刷新数据，并且行也...
