概述
由于<table>
元素在第三方小部件(如日历和日期选择器)中广泛使用,因此 Bootstrap 的表格是 选择加入。将基类.table
添加到任何<table>
,然后使用我们的可选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都可以独立于父表设置样式。
使用最基本的表标记,下面是基于.table
的表在 Bootstrap 中的外观。

变体
使用上下文类为表格、表格行或单个单元格着色。
抬头! 由于用于生成表变体的 CSS 更为复杂,因此它们很可能在 v6 之前看不到颜色模式自适应样式。

辅助功能提示: 使用颜色添加含义仅提供视觉指示,不会传达给屏幕阅读器等辅助技术的用户。请确保从内容本身(例如,可见文本)中可以明显看出含义,或者通过其他方式包含含义,例如使用.visually-hidden
类隐藏的附加文本。

变体和accented表格如何工作?
对于重音表(条纹行、条带列、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
自定义属性设置表格单元格的背景。然后,所有表格变体都设置该自定义属性以为表格单元格着色。这样,如果将半透明颜色用作表格背景,我们就不会遇到麻烦。
- 然后,我们在表格单元格上添加一个带有
box-shadow: inset 0 0 0 9999px var(--bs-table-accent-bg);
的插图框阴影,以在任何指定的 background-color
之上分层。因为我们使用巨大的跨度并且没有模糊,所以颜色将是单调的。由于默认情况下未设置--bs-table-accent-bg
,因此我们没有默认的框阴影。
- 当添加
.table-striped
、.table-striped-columns
、.table-hover
或.table-active
类时,--bs-table-accent-bg
设置为半透明颜色以着色背景。
- 对于每个表格变体,我们生成一个
--bs-table-accent-bg
颜色,其对比度最高,具体取决于该颜色。例如,.table-primary
的主题色较深,而.table-dark
的主题色较浅。
- 文本和边框颜色的生成方式相同,默认情况下会继承它们的颜色。
在幕后,它看起来像这样:
@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));
$table-border-color: mix($color, $background, percentage($table-border-factor));
--#{$prefix}table-color: #{$color};
--#{$prefix}table-bg: #{$background};
--#{$prefix}table-border-color: #{$table-border-color};
--#{$prefix}table-striped-bg: #{$striped-bg};
--#{$prefix}table-striped-color: #{color-contrast($striped-bg)};
--#{$prefix}table-active-bg: #{$active-bg};
--#{$prefix}table-active-color: #{color-contrast($active-bg)};
--#{$prefix}table-hover-bg: #{$hover-bg};
--#{$prefix}table-hover-color: #{color-contrast($hover-bg)};
color: var(--#{$prefix}table-color);
border-color: var(--#{$prefix}table-border-color);
}
}
表格边框
带边框的表
为表格和单元格所有边的边框添加.table-bordered
。

表组分隔符
添加较粗的边框,在表格组(<thead>
、<tbody>
和<tfoot>
)之间添加较暗的边框,并带有.table-group-divider
。通过更改border-top-color
(我们目前不提供实用程序类)来自定义颜色。

垂直对齐
<thead>
的表格单元格始终垂直与底部对齐。<tbody>
中的表格单元格继承自<table>
的对齐方式,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。

嵌套的工作原理
为了防止 any 样式泄漏到嵌套表中,我们在 CSS 中使用了子组合器 (>
) 选择器。由于我们需要定位thead
、tbody
和tfoot
中的所有td
和th
,因此如果没有它,我们的选择器看起来会很长。因此,我们使用看起来相当奇怪的 .table > :not(caption) > * > *
选择器来定位.table
的所有 td
和 th
,而不是任何潜在的嵌套表。
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>
将包装在 <tbody>
中,从而使我们的选择器按预期工作。
剖析(Anatomy)
Table head
与表和深色表类似,使用修饰符类.table-light
或.table-dark
使<thead>
显示为浅灰色或深灰色。

响应式表格
响应式表格允许表格轻松水平滚动。通过将.table
与.table-responsive
包装在一起,使任何表在所有视口中响应。或者,通过使用.table-responsive{-sm|-md|-lg|-xl|-xxl}
选择一个最大断点,以达到响应式表格。
垂直剪切/截断
响应式表格使用overflow-y: hidden
,它剪掉超出表格底部或顶部边缘的任何内容。特别是,这可以剪掉下拉菜单和其他第三方小部件。
始终响应
在每个断点中,使用.table-responsive
进行水平滚动表。

特定于断点
根据需要使用.table-responsive{-sm|-md|-lg|-xl|-xxl}
来创建响应式表格,直到特定断点。从该断点开始及以上,表将正常运行,不会水平滚动。
这些表格可能会显示损坏,直到其响应样式应用于特定的视口宽度。

)用于确定表变体中的对比度。
- 除了浅色和深色表变体外,主题颜色还通过
$table-bg-scale
变量变亮。
