caption不是html5新增的。caption标签是html中用于定义表格标题的，并且该标签必须放置在table标签后，一个表格只能定义一个标题；在html5中已经不支持标签内的align属性，在html4.01时已废弃align属性。

标签定义表格的标题。

标签必须直接放置到 标签之后。

您只能对每个表格定义一个标题。

提示：通常这个标题会被居中于表格之上。然而，CSS 属性 "text-align" 和 "caption-side" 能用来设置标题的对齐方式和显示位置。

HTML5 不支持 align 属性。

HTML 4.01 已废弃 align 属性。

示例如下：

<!DOCTYPE html>
<html>
<head> 
<meta charset="utf-8"> 
<title>123</title> 
</head>
<body>
<table border="1">
  <caption>Monthly savings</caption>
  <tr>
    <th>Month</th>
    <th>Savings</th>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
  <tr>
    <td>February</td>
    <td>$50</td>
  </tr>
</table>
</body>
</html>

输出结果：
