</table>

C:最简单的方法当然是写2个table，用DIV的overflow-y:auto来实现，兼容性绝对没问题，麻烦之处在于2个table的对齐问题，另外用脚本赋予高度的话，需要加onresize()方法。DOM如下：
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=utf-8″ />
<title>无标题文档</title>
<style>
*,body,form,ul,li,p,h1,h2,h3,h4,h5,h6 {margin:0px;padding:0px;}
body, td, th, input, select,p,span{font-family:”微软雅黑”,Arial, Helvetica, sans-serif;}
body,td,div{font-size:12px;color:#333; line-height:150%;-webkit-text-size-adjust:none;}
select{ font-size:12px;}
a {blr:expression(this.onFocus=this.blur()); font-family:”微软雅黑”,Arial, Helvetica, sans-serif; font-size:12px; }
a:link, a:visited {text-decoration:none;color:#333;}
a:hover, a:active {text-decoration:underline;color:#F00;}
ul,li,ol{list-style-type:none;}img {border:none;}
