带有多行的粘性标题表

Question

所以我能够创建一个粘性标题表并且它工作正常。问题是我需要制作另一个带有多行标题的表格，而到目前为止我使用的方法不起作用，正如您在下面的代码中看到的那样。

.table-wrapper {
  position: relative;
  overflow-y: auto;
  height: 200px;
  width: 200px;
}

table {
  border: 1px solid #DDD;
  vertical-align: middle;
  text-align: center;
  border-collapse: collapse;
  border-spacing: 0
}

table tr th,
table tr td{
  border: 1px solid #DDD;
  background-color: #FFF;
  padding: 4px;
}

table thead tr th {
  position: sticky;
  top: 0;
}

<div class="table-wrapper">
  <table>
    <thead>
      <tr>
        <th rowspan="2">
          Header
        </th>
        <th colspan="2">Colspan column</th>
      </tr>
      <tr>
        <th>
          A
        </th>
        <th>
          B
        </th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>Line 1</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 2</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 3</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 4</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 5</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 6</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 7</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 8</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 9</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 10</td>
        <td>a</td>
        <td>b</td>
      </tr>
    </tbody>
  </table>
</div>

是否可以仅使用 CSS 实现我想要的？

你快到了，你可以简单地在你的 <th> 中嵌入一个表格，然后以这种方式添加额外的行。

.table-wrapper {
  position: relative;
  overflow-y: auto;
  height: 200px;
  width: 200px;
}

table {
  border: 1px solid #DDD;
  vertical-align: middle;
  text-align: center;
  border-collapse: collapse;
  border-spacing: 0
}

table tr th,
table tr td{
  border: 1px solid #DDD;
  background-color: #FFF;
  padding: 4px;
}

table thead tr th {
  position: sticky;
  top: 0;
}

<div class="table-wrapper">
  <table>
    <thead>
      <tr>
        <th rowspan="2" colspan="1">
          Header
        </th>
        <th rowspan="2" colspan="2">
        <table>
        <tr>
          <td colspan="2">Colspan column</td>
        </tr>
        <tr>
          <td colspan="1">A</td>
          <td colspan="1">B</td>
        </tr>
        </table>
        </th>
      </tr>
      
    </thead>
    <tbody>
      <tr>
        <td>Line 1</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 2</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 3</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 4</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 5</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 6</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 7</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 8</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 9</td>
        <td>a</td>
        <td>b</td>
      </tr>
      <tr>
        <td>Line 10</td>
        <td>a</td>
        <td>b</td>
      </tr>
    </tbody>
  </table>
</div>

在现代浏览器中，您可以简单地添加 position:sticky（某些 IOS 设备为 -webkit-sticky）。请注意，您需要添加位置：相对于直接容器：如 THEAD、TFoot 或 TBODY。您还需要使用 z-index 设置索引顺序，以便内容在粘性 dom 元素下滚动。因此，如果您有粘性标题并且第一列也是粘性的（是的，这也有效），您需要为它们设置 z-index 级别。

如果您在页眉或页脚单元格上使用带边框的表格，这将无法正常工作，页眉或页脚的边框会随着内容滚动，并在滚动内容时消失。您可以在标题单元格上使用 box-shadow 来模拟边框。

thead,
tbody,
tfoot {
  /* cell container need relative position */
  position: relative;
}


/* sticky header */

thead th {
  /* ios devices */
  position: -webkit-sticky;

  position: sticky;
  left: 0;
  top: 0;

  /* index order is needed for the different sticky levels */
  z-index: 1;

}



/* sticky first column */
thead th:first-of-type {
  top: 0;
  left: 0;
  z-index: 3;
}

tbody td:first-of-type {
  position: -webkit-sticky;
  position: sticky;
  left: 0;
  z-index: 1;

  /* sitcky TD/TH need background color */
  background-color: white;

  /* adding right borde / border gets hidden when scrol so use box-shadow: */
  box-shadow: 2px 0 0 -1px gray;

}


/* sticky footer */

tfoot th {
  position: sticky;
  bottom: 0;
}

tfoot th:first-of-type {
  left: 0;
  z-index: 3;
}





/* default styling */
@import url('https://fonts.googleapis.com/css2?family=Roboto:wght@400;700&display=swap');

* {
  box-sizing: border-box;
}

:root {
  --table-heading: #5D6D7E;
  --table-even: #D5D8DC;
}
body{
    font-family: Roboto, Sans-Serif;
}

.container {
  margin: 1em;
  border: 1px solid grey;
  display: flex;
  max-height: 50vh;
  overflow: auto;


}

table {
  position: relative;
  width: 100%;
  overflow-x: scroll;
  padding: 0;
  margin: 0;
  border-spacing: 0;
}

table thead th,
table tfoot th {
  background-color: var(--table-heading);
  color: white;
}

table td,
table th {
  padding: 0.5em;
  text-align: left;
  margin: 0;
  border: 0;
  border-spacing: 0;
  white-space: nowrap;

}

table tr:nth-child(even) td {
  background-color: var(--table-even);
}
