我想要创建一个固定的表theadtfoot和一个可滚动的tbody

我尝试过几种方法,包括CSS和CSS+Javascript,但是它们都不可靠。

我想达到的效果:

  1. 如果列标题的内容(thead > tr > th)大于列主体的内容(tbody > tr > td),并且大于列页脚的内容(tfoot > tr > td)应根据列标题的大小调整列的大小
  2. 如果列的正文的内容(tbody > tr > td)大于列标题的内容(thead > tr > th),并且大于列页脚的内容(tfoot > tr > td)该列应根据列体的大小调整大小
  3. 如果列的页脚的内容(tfoot > tr > td)大于列标题的内容(thead > tr > th)并且大于列主体的内容(tbody > tr > td)应根据列的页脚大小调整列的大小

table下文应澄清各种设想:

<table>
  <thead>
    <tr>
      <th>Header one *leads the width* (case 1)</th>
      <th>Header two</th>
      <th>Header three</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Column one</td>
      <td>Column two *leads the width* (case 2)</td>
      <td>Column three</td>
    </tr>
  </tbody>
  <tfoot>
    <tr>
      <td>Footer one</td>
      <td>Footer two</td>
      <td>Footer three *leads the width* (case 3)</td>
    </tr>
  </tfoot>
</table>

我希望有一个可靠的解决方案,可以适用于不同的场景,可能只适用于CSS,但JavaScript也可以。我可以接受使用div我该怎么做?

我终于实现了一个可行的解决方案!

有关的CSS如下:

.wrapper {
  width: 90%;
  position: relative;
  border: 1px solid #000;
  background: #efefef;
  overflow: hidden;
  border-radius: 7px;
}

.container {
  overflow-y: auto;
  height: 200px;
  border-top: 41px solid transparent;
  border-bottom: 41px solid transparent;
}

table {
  border-spacing: 0;
  border-collapse: collapse;
  width: 100%;
}

td + td {
  border-left: 1px solid #fff;
}

td, th {
  border-bottom: 1px solid #fff;
  background: #efefef;
  padding: 10px;
}

thead tr th,
tfoot tr td {
  height: 0;
  line-height: 0;
  margin: 0;
  padding-top: 0;
  padding-bottom: 0;
  color: transparent;
  border: none;
  white-space: nowrap;
}

thead tr th div,
tfoot tr td div {
  position: absolute;
  color: #fff;
  height: 20px;
  padding: 10px;
  margin-left: -10px;
  line-height: normal;
  width: 100%;
  z-index: 2;
  text-align: left;
  font-weight: bold;
}

thead tr th div {
  border-left: 1px solid #000;
  border-bottom: 1px solid #000;
}

tfoot tr td div {
  border-top: 1px solid #000;
}

tfoot tr td div.c1,
thead tr th div.c1 {
  background: violet;
}

tfoot tr td div.c2,
thead tr th div.c2 {
  background: green;
}

tfoot tr td div.c3,
thead tr th div.c3 {
  background: yellow;
}

thead tr th div {
  top: 0;
}

tfoot tr td div {
  bottom: 0;
}

thead tr th:first-child div,
tfoot tr td:first-child div {
  border-left: none;
}

这就是标记:

<div class="wrapper">
  <div class="container">
    <table>
      <thead>
        <tr>
          <th>
            Header one *leads the width* (case 1)
            <div class="c1">
              Header one *leads the width* (case 1)
            </div>
          </th>
          <th>
            Header two
            <div class="c2">
              Header two
            </div>
          </th>
          <th>
            Header three
            <div class="c3">
              Header three
            </div>
          </th>
        </tr>

它适用于Chrome、Firefox、Safari和IE11(我不知道它在旧浏览器上的表现如何)。https:/codepen.io/daveoncode/PEN/LNomBE
