由于 <table> 元素在第三方小部件（如日历和日期选择器）中的广泛使用，Bootstrap的表是 opt-in。将基类 .table 添加到任何<table>，然后使用可选的修饰符类或自定义样式进行扩展。所有表样式都不会在 Bootstrap中继承，这意味着任何嵌套表的样式都可以独立于父表。

使用最基本的表标记，以下是基于.table的表在Bootstrap的外观。

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

变体

使用上下文类为表、表行或单个单元格着色。

Class	Heading	Heading
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 tables -->
<table class="table-primary">...</table>
<table class="table-secondary">...</table>
<table class="table-success">...</table>
<table class="table-danger">...</table>
<table class="table-warning">...</table>
<table class="table-info">...</table>
<table class="table-light">...</table>
<table class="table-dark">...</table>

<!-- On rows -->
<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-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>

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，例如使用 .visually-hidden类隐藏的其他文本。

强调表

条纹行

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

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-striped">
  ...
</table>

这些类也可以添加到表变量中：

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-dark table-striped">
  ...
</table>

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-success table-striped">
  ...
</table>

可悬停的行

添加 .table-hover 可对<tbody>中的表行启用悬停状态。

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-hover">
  ...
</table>

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-dark table-hover">
  ...
</table>

这些可悬停的行还可以与条带化变量组合使用：

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-striped table-hover">
  ...
</table>

活动表

通过添加 .table-active类高亮显示表行或单元格。

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table">
  <thead>
    ...
  </thead>
  <tbody>
    <tr class="table-active">
      ...
    </tr>
    <tr>
      ...
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2" class="table-active">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-dark">
  <thead>
    ...
  </thead>
  <tbody>
    <tr class="table-active">
      ...
    </tr>
    <tr>
      ...
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2" class="table-active">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

变体和强调表是如何工作的？

对于强调表（条纹行、可悬停行和活动表），我们使用了一些技术使这些效果适用于所有表变体：

我们首先使用 --bs-table-bg属性设置表单元格的背景。然后，所有表变量都将该自定义属性设置为表单元格着色。这样，如果将半透明的颜色用作表格背景，我们就不会遇到麻烦。
然后，我们在带有background-image: linear-gradient(var(--bs-table-accent-bg), var(--bs-table-accent-bg));的表格单元格上添加一个渐变，到任何指定background-color的顶部。因为 --bs-table-accent-bg在默认情况下是透明的，所以在默认情况下我们有一个不可见的透明线性渐变。
当添加 .table-striped, .table-hover 或 .table-active 类时， --bs-table-accent-bg 被设置为半透明颜色以着色背景。
对于每个表变量，我们生成一个 --bs-table-accent-bg颜色，根据该颜色具有最高的对比度。例如，.table-primary强调文字颜色较深，而.table-dark强调文字颜色较浅。
文本和边框颜色以相同的方式生成，默认情况下继承它们的颜色。

在幕后看起来是这样的：

@mixin table-variant($state, $background) {
  .table-#{$state} {
    $color: color-contrast(opaque($body-bg, $background));
    $hover-bg: mix($color, $background, percentage($table-hover-bg-factor));
    $striped-bg: mix($color, $background, percentage($table-striped-bg-factor));
    $active-bg: mix($color, $background, percentage($table-active-bg-factor));

    --#{$variable-prefix}table-bg: #{$background};
    --#{$variable-prefix}table-striped-bg: #{$striped-bg};
    --#{$variable-prefix}table-striped-color: #{color-contrast($striped-bg)};
    --#{$variable-prefix}table-active-bg: #{$active-bg};
    --#{$variable-prefix}table-active-color: #{color-contrast($active-bg)};
    --#{$variable-prefix}table-hover-bg: #{$hover-bg};
    --#{$variable-prefix}table-hover-color: #{color-contrast($hover-bg)};

    color: $color;
    border-color: mix($color, $background, percentage($table-border-factor));
  }
}

表格边框

边框表

为表格和单元格的所有边添加.table-bordered。

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-bordered">
  ...
</table>

可以添加边框颜色实用程序来更改颜色：

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-bordered border-primary">
  ...
</table>

无边框表

添加 .table-borderless使表格没有边框。

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-borderless">
  ...
</table>

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-dark table-borderless">
  ...
</table>

小尺寸表

添加.table-sm，将所有单元格padding减半，使任何.table 更加紧凑。

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-sm">
  ...
</table>

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry the Bird		@twitter

<table class="table table-dark table-sm">
  ...
</table>

垂直对齐

<thead> 的表格单元格始终与底部垂直对齐。<tbody>中的表格单元格从<table>继承对齐方式，默认情况下与顶部对齐。使用垂直对齐类在需要时重新对齐。

Heading 1	Heading 2	Heading 3	Heading 4
This cell inherits `vertical-align: middle;` from the table	This cell inherits `vertical-align: middle;` from the table	This cell inherits `vertical-align: middle;` from the table	Nulla vitae elit libero, a pharetra augue. Cras mattis consectetur purus sit amet fermentum. Vestibulum id ligula porta felis euismod semper.
This cell inherits `vertical-align: bottom;` from the table row	This cell inherits `vertical-align: bottom;` from the table row	This cell inherits `vertical-align: bottom;` from the table row	Nulla vitae elit libero, a pharetra augue. Cras mattis consectetur purus sit amet fermentum. Vestibulum id ligula porta felis euismod semper.
This cell inherits `vertical-align: middle;` from the table	This cell inherits `vertical-align: middle;` from the table	This cell is aligned to the top.	Nulla vitae elit libero, a pharetra augue. Cras mattis consectetur purus sit amet fermentum. Vestibulum id ligula porta felis euismod semper.

<table class="table table-sm table-dark">
  <div class="table-responsive">
    <table class="table align-middle">
      <thead>
        <tr>
          ...
        </tr>
      </thead>
      <tbody>
        <tr>
          ...
        </tr>
        <tr class="align-bottom">
          ...
        </tr>
        <tr>
          <td>...</td>
          <td>...</td>
          <td class="align-top">This cell is aligned to the top.</td>
          <td>...</td>
        </tr>
      </tbody>
    </table>
  </div>
</table>

嵌套

嵌套表不会继承边框样式、活动样式和表变体。

First

Last

Handle

Mark

Otto

@mdo

Header	Header	Header
A	First	Last
B	First	Last
C	First	Last

Larry

the Bird

@twitter

<table class="table table-striped">
  <thead>
    ...
  </thead>
  <tbody>
    ...
    <tr>
      <td colspan="4">
        <table class="table mb-0">
          ...
        </table>
      </td>
    </tr>
    ...
  </tbody>
</table>

嵌套如何工作

为了防止任何样式泄漏到嵌套表中，我们在CSS中使用子组合符 (>) 选择器。由于我们需要针对thead, tbody, 和 tfoot中的所有td和 th，没有它，我们的选择器看起来会很长。因此，我们使用外观非常奇怪的 .table > :not(caption) > * > *选择器来定位.table的所有 td和th，但没有任何潜在的嵌套表。

请注意，如果将<tr>添加为表的直接子级，则默认情况下，这些 <tr>将被包装在<tbody> 中，从而使选择器按预期工作。

分解

表头

与tables和dark tables类似，使用修饰符类.table-light 或 .table-dark 使 <thead>显示为浅灰色或深灰色。

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter

<table class="table">
  <thead class="table-light">
    ...
  </thead>
  <tbody>
    ...
  </tbody>
</table>

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter

<table class="table">
  <thead class="table-dark">
    ...
  </thead>
  <tbody>
    ...
  </tbody>
</table>

表尾

#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter
Footer	Footer	Footer	Footer

<table class="table">
  <thead>
    ...
  </thead>
  <tbody>
    ...
  </tbody>
  <tfoot>
    ...
  </tfoot>
</table>

字幕

<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 table-sm">
  <caption>List of users</caption>
  <thead>
    ...
  </thead>
  <tbody>
    ...
  </tbody>
</table>

您还可以使用.caption-top将<caption> 放在表的顶部。

List of users
#	First	Last	Handle
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter

<table class="table caption-top">
  <caption>List of users</caption>
  <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>

响应表

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|-xxl}选择一个最大断点，使响应表可以到达该断点。

垂直裁剪/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。

始终响应

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|-xxl}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。

在Sass中定制

因子变量（$table-striped-bg-factor, $table-active-bg-factor & $table-hover-bg-factor）用于确定表变量中的对比度。
除了明暗表变体之外，该$table-bg-level变量还会使主题颜色变亮。
