边框坍塌

​基本用法

¥Basic usage

​坍塌

¥Collapse

尽可能使用 border-collapse 将相邻的单元格边框合并为一个边框。请注意，这包括顶层 <table> 标记上的折叠边框。

¥Use border-collapse to combine adjacent cell borders into a single border when possible. Note that this includes collapsing borders on the top-level <table> tag.

<table class="border-collapse border border-slate-400 ...">
  <thead>
    <tr>
      <th class="border border-slate-300 ...">State</th>
      <th class="border border-slate-300 ...">City</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td class="border border-slate-300 ...">Indiana</td>
      <td class="border border-slate-300 ...">Indianapolis</td>
    </tr>
    <tr>
      <td class="border border-slate-300 ...">Ohio</td>
      <td class="border border-slate-300 ...">Columbus</td>
    </tr>
    <tr>
      <td class="border border-slate-300 ...">Michigan</td>
      <td class="border border-slate-300 ...">Detroit</td>
    </tr>
  </tbody>
</table><table class="border-collapse border border-slate-500 ...">
  <thead>
    <tr>
      <th class="border border-slate-600 ...">State</th>
      <th class="border border-slate-600 ...">City</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td class="border border-slate-700 ...">Indiana</td>
      <td class="border border-slate-700 ...">Indianapolis</td>
    </tr>
    <tr>
      <td class="border border-slate-700 ...">Ohio</td>
      <td class="border border-slate-700 ...">Columbus</td>
    </tr>
    <tr>
      <td class="border border-slate-700 ...">Michigan</td>
      <td class="border border-slate-700 ...">Detroit</td>
    </tr>
  </tbody>
</table>

​分离

¥Separate

使用 border-separate 强制每个单元格显示其自己的单独边框。

¥Use border-separate to force each cell to display its own separate borders.

<table class="border-separate border border-slate-400 ...">
  <thead>
    <tr>
      <th class="border border-slate-300 ...">State</th>
      <th class="border border-slate-300 ...">City</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td class="border border-slate-300 ...">Indiana</td>
      <td class="border border-slate-300 ...">Indianapolis</td>
    </tr>
    <tr>
      <td class="border border-slate-300 ...">Ohio</td>
      <td class="border border-slate-300 ...">Columbus</td>
    </tr>
    <tr>
      <td class="border border-slate-300 ...">Michigan</td>
      <td class="border border-slate-300 ...">Detroit</td>
    </tr>
  </tbody>
</table><table class="border-separate border border-slate-500 ...">
  <thead>
    <tr>
      <th class="border border-slate-600 ...">State</th>
      <th class="border border-slate-600 ...">City</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td class="border border-slate-700 ...">Indiana</td>
      <td class="border border-slate-700 ...">Indianapolis</td>
    </tr>
    <tr>
      <td class="border border-slate-700 ...">Ohio</td>
      <td class="border border-slate-700 ...">Columbus</td>
    </tr>
    <tr>
      <td class="border border-slate-700 ...">Michigan</td>
      <td class="border border-slate-700 ...">Detroit</td>
    </tr>
  </tbody>
</table>

​有条件地应用

​悬停、聚焦和其他状态

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:border-collapse to only apply the border-collapse utility on hover.

<table class="hover:border-collapse">
  <!-- ... -->
</table>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

​断点和媒体查询

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:border-collapse to apply the border-collapse utility at only medium screen sizes and above.

<table class="md:border-collapse">
  <!-- ... -->
</table>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.
