Bootstrap4 通过 .table 类来设置基础表格的样式，实例如下:
<table class="table"> <thead> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> <tr> <td>July</td> <td>Dooley</td> <td>july@example.com</td> </tr> </tbody> </table>
通过添加 .table-striped 类，您将在 <tbody> 内的行上看到条纹，如下面的实例所示：
<table class="table table-striped"> <thead> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> <tr> <td>July</td> <td>Dooley</td> <td>july@example.com</td> </tr> </tbody> </table>
.table-bordered 类可以为表格添加边框
<table class="table table-bordered"> <thead> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> <tr> <td>July</td> <td>Dooley</td> <td>july@example.com</td> </tr> </tbody> </table>
.table-hover 类可以为表格的每一行添加鼠标悬停效果（灰色背景）：
<table class="table table-hover"> <thead> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> <tr> <td>July</td> <td>Dooley</td> <td>july@example.com</td> </tr> </tbody> </table>
<table class="table table-dark"> <thead> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> <tr> <td>July</td> <td>Dooley</td> <td>july@example.com</td> </tr> </tbody> </table>
联合使用 .table-dark 和 .table-striped 类可以创建黑色的条纹表格：
<table class="table table-dark table-striped"> <thead> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> <tr> <td>July</td> <td>Dooley</td> <td>july@example.com</td> </tr> </tbody> </table>
联合使用 .table-dark 和 .table-hover 类可以设置黑色背景表格的鼠标悬停效果：
<table class="table table-dark table-hover"> <thead> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> <tr> <td>July</td> <td>Dooley</td> <td>july@example.com</td> </tr> </tbody> </table>
通过指定意义的颜色类可以为表格的行或者单元格设置颜色：
<table class="table"> <thead> <tr> <th>Firstname</th><th>Lastname</th><th>Email</th> </tr> </thead> <tbody> <tr> <td>Default</td><td>Defaultson</td><td>def@somemail.com</td> </tr> <tr class="table-primary">
<td>Primary</td><td>Joe</td><td>joe@example.com</td> </tr> <tr class="table-success"> <td>Success</td><td>Doe</td><td>john@example.com</td> </tr> <tr class="table-danger"> <td>Danger</td><td>Moe</td><td>mary@example.com</td> </tr> <tr class="table-info"> <td>Info</td><td>Dooley</td><td>july@example.com</td> </tr> <tr class="table-warning"> <td>Warning</td><td>Refs</td><td>bo@example.com</td> </tr> <tr class="table-active"> <td>Active</td><td>Activeson</td><td>act@example.com</td> </tr> <tr class="table-secondary"> <td>Secondary</td><td>Secondson</td><td>sec@example.com</td> </tr> <tr class="table-light"> <td>Light</td><td>Angie</td><td>angie@example.com</td> </tr> <tr class="table-dark text-dark"> <td>Dark</td><td>Bo</td><td>bo@example.com</td> </tr> </tbody> </table>
下表列出了表格颜色类的说明:
.thead-dark 类用于给表头添加黑色背景， .thead-light 类用于给表头添加灰色背景:
<table class="table"> <thead class="thead-dark"> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> </tbody> </table> <table class="table"> <thead class="thead-light"> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> </tbody> </table>
.table-sm 类用于通过减少内边距来设置较小的表格:
<table class="table table-bordered table-sm"> <thead> <tr> <th>Firstname</th> <th>Lastname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>John</td> <td>Doe</td> <td>john@example.com</td> </tr> <tr> <td>Mary</td> <td>Moe</td> <td>mary@example.com</td> </tr> <tr> <td>July</td> <td>Dooley</td> <td>july@example.com</td> </tr> </tbody> </table>
.table-responsive 类用于创建响应式表格：在屏幕宽度小于 992px 时会创建水平滚动条，如果可视区域宽度大于 992px 则显示不同效果（没有滚动条）:
<div class="table-responsive"> <table class="table"> <thead> <tr> <th>#</th> <th>Firstname</th> <th>Lastname</th> <th>Age</th> <th>City</th> <th>Country</th> <th>Sex</th> <th>Example</th> <th>Example</th> <th>Example</th> <th>Example</th> </tr> </thead> <tbody> <tr> <td>1</td> <td>Anna</td> <td>Pitt</td> <td>35</td> <td>New York</td> <td>USA</td> <td>Female</td> <td>Yes</td> <td>Yes</td> <td>Yes</td> <td>Yes</td> </tr> </tbody> </table> </div>
你可以通过以下类设定在指定屏幕宽度下显示滚动条：
