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。
<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-dark
class选择器来产生颜色反转对比效果,即深色背景和浅色文本。
<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。
<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)。
<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>
<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>
表格边框处理
添加 .table-bordered
类可以产生表格边框与间隙系统。
<table class="table table-bordered">
<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>
<table class="table table-bordered 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 colspan="2">Larry the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
无边框
添加.table-borderless
无边界表格
<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>
</tr>
</tbody>
</table>
.table-borderless
也可以用在黑色表格上.
<table class="table table-borderless 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 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)。
<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>
<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。
<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>
<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。
<!-- 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:
<!-- 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。
通过包装任何响应创建表.table
用.table-responsive{-sm|-md|-lg|-xl}
,使表滚动水平在每一个max-width
的断点分别高达576px,768px,992px和1120px,(但不包括)。
min-
和max-
前缀和视口带小数的宽度(可下的高DPI设备一定的条件下发生,例如)通过使用值与这些比较高的精度。
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。
<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。
<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)。
在响应样式应用于特定视口宽度之前,这些表可能会断开.
<div class="table-responsive-sm">
<table class="table">
...
</table>
</div>
<div class="table-responsive-md">
<table class="table">
...
</table>
</div>
<div class="table-responsive-lg">
<table class="table">
...
</table>
</div>
<div class="table-responsive-xl">
<table class="table">
...
</table>
</div>
