使用表格的 HTML 布局

注释:<table> 元素不是作为布局工具而设计的。

<table> 元素的作用是显示表格化的数据。

使用 <table> 元素能够取得布局效果,因为能够通过 CSS 设置表格元素的样式:

<body>

<table class="lamp">
<tr>
  <th>
    <img src="/images/lamp.jpg" alt="Note" style="height:32px;width:32px">
  </th>
  <td>
    The table element was not designed to be a layout tool.
  </td>
</tr>
</table>

</body>
