html - 表格固定标题和可滚动正文

Question

我正在尝试使用 bootstrap 3 表制作一个带有固定标题和可滚动内容的表。不幸的是，我找到的解决方案不适用于 bootstrap 或破坏样式。

这里有一个简单的 Bootstrap 表，但由于某种原因，我不知道 tbody 的高度不是 10px。

height: 10px !important; overflow: scroll;

例子:

<link rel="stylesheet" type="text/css" href="//netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css">

<table class="table table-striped">
    <thead>
    <tr>
        <th>Make</th>
        <th>Model</th>
        <th>Color</th>
        <th>Year</th>
    </tr>
    </thead>
    <tbody style="height: 10px !important; overflow: scroll; ">
    <tr>
        <td class="filterable-cell">111 Ford</td>
        <td class="filterable-cell">Escort</td>
        <td class="filterable-cell">Blue</td>
        <td class="filterable-cell">2000</td>
    </tr>
    <tr>
        <td class="filterable-cell">Ford</td>
        <td class="filterable-cell">Escort</td>
        <td class="filterable-cell">Blue</td>
        <td class="filterable-cell">2000</td>
    </tr>
            <tr>
        <td class="filterable-cell">Ford</td>
        <td class="filterable-cell">Escort</td>
        <td class="filterable-cell">Blue</td>
        <td class="filterable-cell">2000</td>
    </tr>
     <tr>
        <td class="filterable-cell">Ford</td>
        <td class="filterable-cell">Escort</td>
        <td class="filterable-cell">Blue</td>
        <td class="filterable-cell">2000</td>
    </tr>
    </tbody>
    
</table>

固定表头 - 仅 CSS

简单位置:粘性； top: 0; 你的 th 元素。 (Chrome、FF、Edge)

.tableFixHead          { overflow: auto; height: 100px; }
.tableFixHead thead th { position: sticky; top: 0; z-index: 1; }

/* Just common table stuff. Really. */
table  { border-collapse: collapse; width: 100%; }
th, td { padding: 8px 16px; }
th     { background:#eee; }

<div class="tableFixHead">
  <table>
    <thead>
      <tr><th>TH 1</th><th>TH 2</th></tr>
    </thead>
    <tbody>
      <tr><td>A1</td><td>A2</td></tr>
      <tr><td>B1</td><td>B2</td></tr>
      <tr><td>C1</td><td>C2</td></tr>
      <tr><td>D1</td><td>D2</td></tr>
      <tr><td>E1</td><td>E2</td></tr>
    </tbody>
  </table>
</div>

对于两个 sticky vertical TH and horizontal TH columns (inside TBODY) :

.tableFixHead          { overflow: auto; height: 100px; width: 240px; }
.tableFixHead thead th { position: sticky; top: 0; z-index: 1; }
.tableFixHead tbody th { position: sticky; left: 0; }

.tableFixHead          { overflow: auto; height: 100px; width: 240px; }
.tableFixHead thead th { position: sticky; top: 0; z-index: 1; }
.tableFixHead tbody th { position: sticky; left: 0; }

/* Just common table stuff. Really. */
table  { border-collapse: collapse; width: 100%; }
th, td { padding: 8px 16px; white-space: nowrap; }
th     { background:#eee; }

<div class="tableFixHead">
  <table>
    <thead>
      <tr><th></th><th>TH 1</th><th>TH 2</th></tr>
    </thead>
    <tbody>
            <tr><th>Foo</th><td>Some long text lorem ipsum</td><td>Dolor sit amet</td></tr>
            <tr><th>Bar</th><td>B1</td><td>B2</td></tr>
            <tr><th>Baz</th><td>C1</td><td>C2</td></tr>
            <tr><th>Fuz</th><td>D1</td><td>D2</td></tr>
            <tr><th>Zup</th><td>E1</td><td>E2</td></tr>
    </tbody>
  </table>
</div>

TH 边框问题修复

由于 border 无法正确绘制在已翻译的 TH 元素上，重新创建和渲染 "borders" 使用 box-shadow 属性:

/* Borders (if you need them) */
.tableFixHead,
.tableFixHead td {
  box-shadow: inset 1px -1px #000;
}
.tableFixHead th {
  box-shadow: inset 1px 1px #000, 0 1px #000;
}

.tableFixHead          { overflow: auto; height: 100px; }
.tableFixHead thead th { position: sticky; top: 0; z-index: 1; }

/* Just common table stuff. Really. */
table  { border-collapse: collapse; width: 100%; }
th, td { padding: 8px 16px; }
th     { background:#eee; }

/* Borders (if you need them) */
.tableFixHead,
.tableFixHead td {
  box-shadow: inset 1px -1px #000;
}
.tableFixHead th {
  box-shadow: inset 1px 1px #000, 0 1px #000;
}

<div class="tableFixHead">
  <table>
    <thead>
      <tr><th>TH 1</th><th>TH 2</th></tr>
    </thead>
    <tbody>
      <tr><td>A1</td><td>A2</td></tr>
      <tr><td>B1</td><td>B2</td></tr>
      <tr><td>C1</td><td>C2</td></tr>
      <tr><td>D1</td><td>D2</td></tr>
      <tr><td>E1</td><td>E2</td></tr>
    </tbody>
  </table>
</div>

TH 粘滞不工作修复

确保“th”元素的父元素，至少在table元素(包括)之前，不设置 overflow 相关样式(例如overflow、overflow-x、overflow-y)。

固定表头 - 使用 JS。 (IE)

你可以使用一点 JS 和 translateY th 元素

jQuery 示例

var $th = $('.tableFixHead').find('thead th')
$('.tableFixHead').on('scroll', function() {
  $th.css('transform', 'translateY('+ this.scrollTop +'px)');
});

.tableFixHead { overflow-y: auto; height: 100px; }

/* Just common table stuff. */
table  { border-collapse: collapse; width: 100%; }
th, td { padding: 8px 16px; }
th     { background:#eee; }

<div class="tableFixHead">
  <table>
    <thead>
      <tr><th>TH 1</th><th>TH 2</th></tr>
    </thead>
    <tbody>
      <tr><td>A1</td><td>A2</td></tr>
      <tr><td>B1</td><td>B2</td></tr>
      <tr><td>C1</td><td>C2</td></tr>
      <tr><td>D1</td><td>D2</td></tr>
      <tr><td>E1</td><td>E2</td></tr>
    </tbody>
  </table>
</div>

<script src="https://code.jquery.com/jquery-3.1.0.js"></script>

如果您愿意，也可以使用纯 ES6(不需要 jQuery):

// Fix table head
function tableFixHead (e) {
    const el = e.target,
          sT = el.scrollTop;
    el.querySelectorAll("thead th").forEach(th => 
      th.style.transform = `translateY(${sT}px)`
    );
}
document.querySelectorAll(".tableFixHead").forEach(el => 
    el.addEventListener("scroll", tableFixHead)
);
