如何在CSS中以百分比形式制作表格和单元格宽度的固定标题表？

Question

我找到了固定头表的以下解决方案:

table {
  width: 450px;
  border-collapse: collapse;
}

thead {
  display: block;
  width: 450px;
  overflow: auto;
  color: #fff;
  background: #000;
}

tbody {
  display: block;
  width: 450px;
  height: 200px;
  background: pink;
  overflow: auto;
}

th,
td {
  padding: 0;
  text-align: left;
  vertical-align: top;
  border-left: 1px solid #fff;
}

<table>
  <thead>
    <tr>
      <th style="width:200px">Header 1</th>
      <th style="width:200px">Header 2</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td style="width:200px">Cell 1, Row 1</td>
      <td style="width:200px">Cell 2, Row 1</td>
    </tr>
    <tr>
      <td>Cell 1, Row 2</td>
      <td>Cell 2, Row 2</td>
    </tr>
    <tr>
      <td>Cell 1, Row 3</td>
      <td>Cell 2, Row 3</td>
    </tr>
    <tr>
      <td>Cell 1, Row 4</td>
      <td>Cell 2, Row 4</td>
    </tr>
    <tr>
      <td>Cell 1, Row 5</td>
      <td>Cell 2, Row 5</td>
    </tr>
    <tr>
      <td>Cell 1, Row 6</td>
      <td>Cell 2, Row 6</td>
    </tr>
    <tr>
      <td>Cell 1, Row 7</td>
      <td>Cell 2, Row 7</td>
    </tr>
    <tr>
      <td>Cell 1, Row 8</td>
      <td>Cell 2, Row 8</td>
    </tr>
    <tr>
      <td>Cell 1, Row 9</td>
      <td>Cell 2, Row 9</td>
    </tr>
    <tr>
      <td>Cell 1, Row 10</td>
      <td>Cell 2, Row 10</td>
    </tr>
    <tr>
      <td>Cell 1, Row 11</td>
      <td>Cell 2, Row 11</td>
    </tr>
    <tr>
      <td>Cell 1, Row 12</td>
      <td>Cell 2, Row 12</td>
    </tr>
  </tbody>
</table>

此解决方案的问题在于它为表格和单元格设置固定宽度(以像素为单位).但是,我需要<table style="width:100%">和<td style="width:X%">.如何使用一个 html表并且没有JS ,使CSS中的表和单元格宽度以百分比形式固定表头？

检查发布在不同问题上的解决方案。 固定标头解决方案。

或者直接尝试这个Fiddle

标题内容放置在“th”中的“div”内。该 div 具有绝对位置和其他样式，以将标题显示为固定。

html, body{
  margin:0;
  padding:0;
  height:100%;
}
section {
  position: relative;
  border: 1px solid #000;
  padding-top: 37px;
  background: #500;
}
section.positioned {
  position: absolute;
  top:100px;
  left:100px;
  width:800px;
  box-shadow: 0 0 15px #333;
}
.container {
  overflow-y: auto;
  height: 200px;
}
table {
  border-spacing: 0;
  width:100%;
}
td + td {
  border-left:1px solid #eee;
}
td, th {
  border-bottom:1px solid #eee;
  background: #ddd;
  color: #000;
  padding: 10px 25px;
}
th {
  height: 0;
  line-height: 0;
  padding-top: 0;
  padding-bottom: 0;
  color: transparent;
  border: none;
  white-space: nowrap;
}
th div{
  position: absolute;
  background: transparent;
  color: #fff;
  padding: 9px 25px;
  top: 0;
  margin-left: -25px;
  line-height: normal;
  border-left: 1px solid #800;
}
th:first-child div{
  border: none;
}
