上面是實際效果，雖然丑陋。不過當時寫這個效果的時候也并不順利。
代碼如下：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<style>
#tab
{
table-layout:auto;
border-collapse:collapse;
border:1px solid #000000;
width:100%;
}
div
{
width:100%;
margin:0px;
padding:0px;
overflow:auto;
border: 1px solid #4CA2ED;
background-color:#E8F2FE;
font-size:9pt;
}
td
{
position:relative;
padding:0px;
margin:0px;
}
</style>
<script type="text/javascript">

{

$('td2').pareneTdH = $('td2').offsetHeight;
$('td3').pareneTdH = $('td3').offsetHeight;
$('tab').pareneTableH = $('tab').offsetHeight;
obj.setCapture();//事件擴張
}
function MouseMoveToResize(obj)
{
if(!obj.mouseDownY) return false;
var newHeight = $('td2').pareneTdH*1+event.clientY*1-obj.mouseDownY;
//拖動
if((newHeight<0 && -1*newHeight<$('td1').pareneTdH )||(newHeight>0 && newHeight<$('td3').pareneTdH))
{
