HTML 标签

HTML <colgroup> tag

所有主流浏览器都支持 标签。 (推荐学习：HTML入门教程)

Firefox、Chrome 以及 Safari 仅支持 colgroup 元素的 span 和 width 属性。

定义和用法

标签用于对表格中的列进行组合，以便对其进行格式化。

如需对全部列应用样式， 标签很有用，这样就不需要对各个单元和各行重复应用样式了。

标签只能在 table 元素中使用。

提示

提示：请为 标签添加 class 属性。这样就可以使用 CSS 来负责对齐方式、宽度和颜色等等。

注：col 元素是仅包含属性的空元素。如需创建列，您就必须在 tr 元素内部规定 td 元素。

实例

两个 colgroup 元素为表格中的三列规定了不同的对齐方式和样式（注意第一个 colgroup 元素横跨两列）：

<html>
<body>

<table width="100%" border="1">
  <colgroup span="2" align="left"></colgroup>
  <colgroup align="right" style="color:#0000FF;"></colgroup>
  <tr>
    <th>ISBN</th>
    <th>Title</th>
    <th>Price</th>
  </tr>
  <tr>
    <td>3476896</td>
    <td>My first HTML</td>
    <td>$53</td>
  </tr>
  <tr>
    <td>2489604</td>
    <td>My first CSS</td>
    <td>$47</td>
  </tr>
</table>

</body>
</html>
Copy after login
