表格

使用Bootstrap的表格的opt-in样式的文档和示例（考虑到它们在JavaScript插件中的普遍使用）。

示例

由于表格在第三方小部件（如日历和日期选择器）中的广泛使用，我们将表格设计为 opt-in。只需将基类 .table 添加到任何 <table>，然后使用自定义样式或我们包含的各种修饰符类进行扩展。

使用最基本的表标记，以下是基于 .table的表在 Bootstrap中的外观。 所有表样式都在Bootstrap 4中继承，这意味着任何嵌套表的样式都将与父表的样式相同。

# First Last Handle
1 Mark Otto @mdo
2 Jacob Thornton @fat
3 Larry the Bird @twitter 
<table class="table">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First</th>
      <th scope="col">Last</th>
      <th scope="col">Handle</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td>Larry</td>
      <td>the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

你也可以用 .table-dark在深色背景上用浅色文本反转颜色。

# First Last Handle
1 Mark Otto @mdo
2 Jacob Thornton @fat
3 Larry the Bird @twitter 
<table class="table table-dark">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First</th>
      <th scope="col">Last</th>
      <th scope="col">Handle</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td>Larry</td>
      <td>the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

表头选项

与表格和深色表格类似，请使用修改器类 .thead-light 或 .thead-dark 使 <thead>显示为浅灰色或深灰色。

条纹行

使用 .table-striped 将斑纹条纹添加到<tbody>中的任何表行。

<table class="table table-bordered">

无边的表格

添加 .table-borderless 的表来说是无边框的。

# First Last Handle
1 Mark Otto @mdo
2 Jacob Thornton @fat
3 Larry the Bird @twitter 
<table class="table table-borderless">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First</th>
      <th scope="col">Last</th>
      <th scope="col">Handle</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>

.table-borderless 也可用于深色表。

    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>

    <tr>
      <th scope="row">3</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>

      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>

添加 .table-sm 通过将单元格填充减半使表格更加紧凑。

      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

上下文类

使用上下文类为表行或单个单元格着色。

Class Heading Heading
Active Cell Cell
Default Cell Cell
Primary Cell Cell
Secondary Cell Cell
Success Cell Cell
Danger Cell Cell
Warning Cell Cell
Info Cell Cell
Light Cell Cell
Dark Cell Cell 
<!-- On rows -->
<tr class="table-active">...</tr>
<tr class="table-primary">...</tr>
<tr class="table-secondary">...</tr>
<tr class="table-success">...</tr>
<tr class="table-danger">...</tr>
<tr class="table-warning">...</tr>
<tr class="table-info">...</tr>
<tr class="table-light">...</tr>
<tr class="table-dark">...</tr>

<!-- On cells (`td` or `th`) -->
<tr>
  <td class="table-active">...</td>
  <td class="table-primary">...</td>
  <td class="table-secondary">...</td>
  <td class="table-success">...</td>
  <td class="table-danger">...</td>
  <td class="table-warning">...</td>
  <td class="table-info">...</td>
  <td class="table-light">...</td>
  <td class="table-dark">...</td>
</tr>

常规表格背景变量不适用于深色表格，但是，您可以使用 文本或背景实用程序 实现类似的样式。

# Heading Heading
1 Cell Cell
2 Cell Cell
3 Cell Cell
4 Cell Cell
5 Cell Cell
6 Cell Cell
7 Cell Cell
8 Cell Cell
9 Cell Cell 
<!-- On rows -->
<tr class="bg-primary">...</tr>
<tr class="bg-success">...</tr>
<tr class="bg-warning">...</tr>
<tr class="bg-danger">...</tr>
<tr class="bg-info">...</tr>

<!-- On cells (`td` or `th`) -->
<tr>
  <td class="bg-primary">...</td>
  <td class="bg-success">...</td>
  <td class="bg-warning">...</td>
  <td class="bg-danger">...</td>
  <td class="bg-info">...</td>
</tr>
向辅助技术传达意义

使用颜色来增加意义只会提供一种视觉指示，而不会传达给辅助技术（如屏幕阅读器）的用户。确保由颜色表示的信息在内容本身（例如可见文本）中是明显的，或者通过其他方式包含，例如用 .sr-only类隐藏的其他文本。

通过使用 .table-responsive{-sm|-md|-lg|-xl}包装任何.table 来创建响应表，使表在每个 max-width 断点处水平滚动，每个断点分别高达（但不包括）576px、768px、992px和1120px。

请注意，由于浏览器当前不支持 范围上下文查询，因此我们通过使用精度更高的值进行这些比较，绕过了 min- 和 max- 前缀以及具有分数宽度的视口（例如，在某些条件下，在高dpi设备上可能出现这种情况）的限制。

字幕（caption）

<caption> 的功能类似于表格的标题。它帮助屏幕阅读器的用户找到一个表，了解它的内容，并决定他们是否要阅读它。

List of users
# First Last Handle
1 Mark Otto @mdo
2 Jacob Thornton @fat
3 Larry the Bird @twitter 
<table class="table">

  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First</th>
      <th scope="col">Last</th>
      <th scope="col">Handle</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>

      <td>Larry</td>
      <td>the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

响应式表格

响应表允许轻松地水平滚动表。通过将 .table 包装为 .table-responsive，使所有视口中的任何表都具有响应性。或者，通过使用 .table-responsive{-sm|-md|-lg|-xl}选择一个最大断点，使响应表可以到达该断点。

垂直剪裁/截断

响应表使用overflow-y: hidden，它可以剪裁超出表的底部或顶部边缘的任何内容。特别是，这可以剪辑掉下拉菜单和其他第三方小部件。

总是响应式

在每个断点上，使用 .table-responsive 来水平滚动表。

# Heading Heading Heading Heading Heading Heading Heading Heading Heading
1 Cell Cell Cell Cell Cell Cell Cell Cell Cell
2 Cell Cell Cell Cell Cell Cell Cell Cell Cell
3 Cell Cell Cell Cell Cell Cell Cell Cell Cell 
<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

特定于断点

根据需要使用 .table-responsive{-sm|-md|-lg|-xl} 创建到达特定断点的响应表。从该断点开始，表将正常运行，不会水平滚动。

这些表可能会显示为断开，直到它们的响应样式应用于特定的视口宽度。
