html - css 表格列不会与固定标题对齐

Question

我一直在尝试制作一个可滚动的表格，但我的标题和我的列不会对齐......我也希望它跨越整个宽度 (100%)，但我还没有解决这个问题......这是原始代码，我提供了一个链接，指向我的表格设计的 CSS fiddle 查询和我目前的进度...

我的最终目标；

1. 让表格横跨页面的整个宽度
2. 静态标题
3. 让表体可滚动

HTML

<table class="fixed_header">
  <thead>
    <tr>
      <th>Col 1</th>
      <th>Col 2</th>
      <th>Col 3</th>
      <th>Col 4</th>
      <th>Col 5</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>row 1-0</td>
      <td>row 1-1</td>
      <td>row 1-2</td>
      <td>row 1-3</td>
      <td>row 1-4</td>
    </tr>
    <tr>
      <td>row 2-0</td>
      <td>row 2-1</td>
      <td>row 2-2</td>
      <td>row 2-3</td>
      <td>row 2-4</td>
    </tr>
    <tr>
      <td>row 3-0</td>
      <td>row 3-1</td>
      <td>row 3-2</td>
      <td>row 3-3</td>
      <td>row 3-4</td>
    </tr>
    <tr>
      <td>row 4-0</td>
      <td>row 4-1</td>
      <td>row 4-2</td>
      <td>row 4-3</td>
      <td>row 4-4</td>
    </tr>
  </tbody>
</table>

CSS:

Answer 1

演示:https://jsfiddle.net/ap4ognvz/64/

我已将以下内容添加到您的 CSS 中:

tr {
  display: table;
  width: 100%;
  table-layout: fixed;
}

所以你的最终 CSS 看起来像下面这样:

.fixed_header tbody {
  display: block;
  overflow-y: scroll;
  overflow-x: hidden;
  height: 100px;
}

.fixed_header thead tr {
  height: 20px;
}

table {
  border-collapse: collapse;
}

table tr {
  background-color: #f8f8f8;
  border: 1px solid #ddd;
  padding: .35em;
}

table th {
  background-color: #545556;
  color: white;
  padding: .425em;
  text-align: center;
}

table td {
  padding: .425em;
  text-align: center;
  word-wrap: break-word;
  font-size: 0.75em;
}

table th {
  font-size: .75em;
  letter-spacing: .1em;
  text-transform: uppercase;
}

tr {
  display: table;
  width: 100%;
  table-layout: fixed;
}
