表格

使用Bootstrap使用表格的文档和示例（表格样式及响应式优先于BootStrap全局的其它JavaScript事件）。

示例

在第三方部件例如日历和日期选择器中广泛使用表格，我们设计了视情况需要加入的表格类。只需要向某个<table>添加一个基类.table，然后通过自定义样式或系统提供的class来起作用。

使用最基本的表格标记，下面是Bootstrap中 .table表格的样式（基本样式）， Bootstrap 4继承了所有的表格样式，这意味着任何嵌套表格都将以与父类型相同的方式进行样式化。

#	First Name	Last Name	Username
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 Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

你可使用.table-darkclass选择器来产生颜色反转对比效果，即深色背景和浅色文本。

#	First Name	Last Name	Username
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 Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

Head表头处理

与预设的反转样式相似，使用.thead-light 或.thead-dark 中的一个样式，就能使 <thead>区显示出浅黑或深灰。

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

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

<table class="table">
  <thead class="thead-dark">
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

<table class="table">
  <thead class="thead-light">
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

条纹状表格

使用 .table-striped 样式定义 <tbody>，可以产生逐行颜色强烈对比的表格样式（以及增加反转）。

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

<table class="table table-striped">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

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

<table class="table table-striped table-dark">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

Bordered table

添加 .table-bordered 类可以产生表格边框与间隙系统。

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
2	Mark	Otto	@TwBootstrap
3	Jacob	Thornton	@fat
4	Larry the Bird		@twitter

<table class="table table-bordered">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>Mark</td>
      <td>Otto</td>
      <td>@TwBootstrap</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">4</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
2	Mark	Otto	@TwBootstrap
3	Jacob	Thornton	@fat
4	Larry the Bird		@twitter

<table class="table table-bordered table-dark">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>Mark</td>
      <td>Otto</td>
      <td>@TwBootstrap</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">4</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

行悬停效果

将 .table-hover 定义到 <tbody>上，可以产生行悬停效果（鼠标移到行上会出现状态提示）。

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

<table class="table table-hover">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

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

<table class="table table-hover table-dark">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

紧缩表格

添加 .table-sm 可以将表格的padding值缩减一半，使表格更加紧凑。

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

<table class="table table-sm">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

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

<table class="table table-sm table-dark">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

语义状态化

使用语义状态样式对表格逐行或单个单元格进行着色表达。

Type	Column heading	Column heading	Column heading
Active	Column content	Column content	Column content
Default	Column content	Column content	Column content
Primary	Column content	Column content	Column content
Secondary	Column content	Column content	Column content
Success	Column content	Column content	Column content
Danger	Column content	Column content	Column content
Warning	Column content	Column content	Column content
Info	Column content	Column content	Column content
Light	Column content	Column content	Column content
Dark	Column content	Column content	Column content

<!-- 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>

深色表格上没有固定的背景，你可以使用文字或背景通用样式获得类似的样式：

#	Column heading	Column heading	Column heading
1	Column content	Column content	Column content
2	Column content	Column content	Column content
3	Column content	Column content	Column content
4	Column content	Column content	Column content
5	Column content	Column content	Column content
6	Column content	Column content	Column content
7	Column content	Column content	Column content
8	Column content	Column content	Column content
9	Column content	Column content	Column content

<!-- 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>

向使用辅助技术的用户传达用意

使用颜色添加意义只提供一个视觉指示，这不会传达给辅助技术的用户，如屏幕阅读器。确保由颜色表示的信息从内容本身（例如可见文本）中显而易见，或者通过替代方法包括，例如隐藏在.sr-only该类中的附加文本。

Captions表格辅助标题

<caption> 标签如同一个表格的标题，它默认是隐藏的，可以协助屏幕阅读器用户找到表格、了解表格内容，且决定是否需要阅读它。

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

<table class="table">
  <caption>List of users</caption>
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First Name</th>
      <th scope="col">Last Name</th>
      <th scope="col">Username</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>

响应式表格

当表格想要始终呈现水平滚动，可在.table上加入.table-responsive获得响应式表现，从而支持任何viewport窗口。也可以在.table上，加 .table-responsive{-sm|-md|-lg|-xl}属性来定义多屏幕尺寸响应支持。

垂直剪裁/缩减

当响应式表格超过表格底部或顶部边缘，会通过 overflow-y: hidden属性将内容隐藏，总的说这会隐藏掉下拉列表或第三方的插件展现。

总是响应

为兼容各个屏幕规格断点，添加 .table-responsive 选择器使表格支持水平响应。

#	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>

多屏幕断点设定

使用 .table-responsive{-sm|-md|-lg|-xl}可以根据需要对不同屏幕尺寸断点表格进行响应式设计，在中断点之上该表格会正常显示，而不是水平滚动（没有水平条）。

#	Heading	Heading	Heading	Heading	Heading
1	Cell	Cell	Cell	Cell	Cell
2	Cell	Cell	Cell	Cell	Cell
3	Cell	Cell	Cell	Cell	Cell

#	Heading	Heading	Heading	Heading	Heading
1	Cell	Cell	Cell	Cell	Cell
2	Cell	Cell	Cell	Cell	Cell
3	Cell	Cell	Cell	Cell	Cell

#	Heading	Heading	Heading	Heading	Heading
1	Cell	Cell	Cell	Cell	Cell
2	Cell	Cell	Cell	Cell	Cell
3	Cell	Cell	Cell	Cell	Cell

#	Heading	Heading	Heading	Heading	Heading
1	Cell	Cell	Cell	Cell	Cell
2	Cell	Cell	Cell	Cell	Cell
3	Cell	Cell	Cell	Cell	Cell

<div class="table-responsive-sm">

  </table>
</div>
