html5中标签作用是定义表格中一个或多个列属性值，这里详细介绍下标签用法、标签属性以及标签应用实例。

html中标签作用：定义表格中一个或多个列属性值

标签用法：

标签为表格中一个或多个列定义属性值。

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。

您只能在 table 或 colgroup 元素中使用 标签。

标签应用实例：

col 元素为表格中的三个列规定了不同的对齐方式：

<table width="100%" border="1">  <col align="left" />
  <col align="left" />
  <col align="right" />
  <tr>
    <th>ISBN</th>
    <th>Title</th>
    <th>Price</th>
  </tr>
  <tr>
    <td>3476896</td>
    <td>My first HTML</td>
    <td>$53</td>
  </tr>
</table>
Copy after login

标签有哪些属性？

哪些浏览器支持标签？

所有主流浏览器都支持标签。

html中col标签的实例

<html>
<body>
<table border="2">
<col span="2" style="color:red">
<col style="color:blue">
<tr>
<td>红色</td>
<td>红色</td>
<td>蓝色</td>
</tr>
<tr>
<td>红色</td>
<td>红色</td>
<td>蓝色</td>
</tr>
</table>
</body>
</html>
Copy after login

这样就可以给每一列设置样式，而不用在每个td里面设置。

第一二两列是红的。第三列是蓝的。
