<p>Try like this :</p>

<p>In this example i just used textbox instead of your input types </p>

<p><strong>table like</strong> </p>

<pre><code>&lt;table class="table table-striped table-bordered"&gt;
    &lt;thead&gt;
        &lt;tr&gt;
            &lt;th&gt;Code&lt;/th&gt;
            &lt;th&gt;Name&lt;/th&gt;
            &lt;th&gt;Price&lt;/th&gt;
            &lt;th&gt;Action&lt;/th&gt;
        &lt;/tr&gt;
    &lt;/thead&gt;
    &lt;tbody&gt;
        &lt;tr *ngFor="let field of fieldArray; let i = index"&gt;
            &lt;td&gt;
                &lt;input [(ngModel)]="field.code" class="form-control" type="text" name="{{field.code}}" /&gt;
            &lt;/td&gt;
            &lt;td&gt;
                &lt;input [(ngModel)]="field.name" class="form-control" type="text" name="{{field.name}}" /&gt;
            &lt;/td&gt;
            &lt;td&gt;
                &lt;input [(ngModel)]="field.price" class="form-control" type="text" name="{{field.price}}" /&gt;
            &lt;/td&gt;
            &lt;td&gt;
                &lt;button class="btn btn-default"  type="button" (click)="deleteFieldValue(i)"&gt;Delete&lt;/button&gt;
            &lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;td&gt;
                &lt;input class="form-control" type="text" id="newAttributeCode" [(ngModel)]="newAttribute.code" name="newAttributeCode" /&gt;
            &lt;/td&gt;
            &lt;td&gt;
                &lt;input class="form-control" type="text" id="newAttributeName" [(ngModel)]="newAttribute.name" name="newAttributeName" /&gt;
            &lt;/td&gt;
            &lt;td&gt;
                &lt;input class="form-control" type="text" id="newAttributePrice" [(ngModel)]="newAttribute.price" name="newAttributePrice" /&gt;
            &lt;/td&gt;
            &lt;td&gt;
                &lt;button class="btn btn-default" type="button" (click)="addFieldValue()"&gt;Add&lt;/button&gt;
            &lt;/td&gt;
        &lt;/tr&gt;
    &lt;/tbody&gt;
&lt;/table&gt;
</code></pre>

<p><strong>typescript sample :</strong></p>

<pre><code>export class Component {
    private fieldArray: Array&lt;any&gt; = [];
    private newAttribute: any = {};

    addFieldValue() {
        this.fieldArray.push(this.newAttribute)
        this.newAttribute = {};
    }

    deleteFieldValue(index) {
        this.fieldArray.splice(index, 1);
    }
}
</code></pre>


blocks|key|4537003|text|只需添加具有相同字段的两行。具有相同字段的一个将避免fieldArray初始为null，而具有相同字段的另一个用于*+and，如下所示|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4537004|<table>

<tr>
</tr>

<tr+*ngFor>
</tr>

</table>|code-block|syntax|javascript|4537005|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<p>Just add two row with same field. one with same field  will avoid fieldArray initially null  and one with same Field for *ngFor like this </p>

<pre><code>&lt;table&gt;

&lt;tr&gt;
&lt;/tr&gt;

&lt;tr *ngFor&gt;
&lt;/tr&gt;

&lt;/table&gt;
</code></pre>

<p>In my angular app, I have 3 inputs say - code, name and price. And there is a table that displays the user selection.
<a href="https://i.stack.imgur.com/o770g.png" rel="noreferrer"><img src="https://i.stack.imgur.com/o770g.png" alt="enter image description here"></a></p>

<p>When I click on the add button, the selection from the dropdown should get populated to the table as,</p>

<pre><code>Product     Price      Action
124578-ABC  100        &lt;Delete Button&gt;
</code></pre>

<p>When I click on the delete button, the corresponding row should get deleted.
I tried doing this using jquery. But I want to know the angular way of doing it.</p>
