表格特有的元素
<summary>:same as "alt" in <img>
<caption>:title
<thead>:逻辑部分
<tfoot>:逻辑部分
<tbody>:逻辑部分
<col>:可以给每个标题的<th>设置scope属性，表示与列相关
表单特有的元素
<fieldset>:对相关信息分组
<legend>:fieldset的标题，一般在fieldset上方居中，很难应用样式
<lable>:用lable与表单元素联系
有两种方法
- 隐式：
<pre><lable>email<input name="email" type="text"></lable></pre> - 显示：
<pre><lable for="email">email</lable> <input name="email" id="email" type="text"></pre>
仿照书上例子画的表格：
<pre>
`
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Top 3 play list</title>
<style type="text/css">
</style>
</head>
<body>
<table cellspacing="0" class="cal" summary="Top 3 play list">
<caption>Top 3 play list</caption>
<colgroup>
<col id="Entry" />
<col id="Track" />
<col id="Artist" />
<col id="Album" />
</colgroup>
<thead>
<tr>
<th id="Entry" scope="col">Entry</th>
<th scope="col">Track</th>
<th scope="col">Artist</th>
<th scope="col">Album</th>

要实现看起来很见到的例子都好难啊，很多细节要考虑，盒模型很重要的样子。
