工作就是这样，你可以选择在安逸空间里晒太阳;也可以选择通过自我提升来品味另一空间的气候...

直接为div指定overflow属性为auto即可，但是必须指定div的高度，如下：
<div style="position:absolute; height:400px; overflow:auto"> </div>
如果要出现水平滚动条，则： overflow-x:auto 同理，垂直滚动条为： overflow-y:auto 如果该div被包含在其他对象例如td中，则位置可设为相对：position:relative
例如：
<html>
<head>
<title>测试表格内的滚动条</title>
</head>
<body>
<table>
<tr>
<td>表格内的滚动条:</td>
<td>
<div id="wins" style="position:absolute;height:200;200;overflow:auto;background:#EEEEEE;">
<p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p>
<p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
</div>
</td>
</tr>
<tr>
<td colspan="2" align="right">
<span onmouseover='scrollb=setInterval("wins.scrollLeft-=10",100)' onmouseout=clearInterval(scrollb)>向左</span>
<span onmouseover='scrollb=setInterval("wins.scrollTop-=10",100)' onmouseout=clearInterval(scrollb)>向上</span>
<span onmouseover='scrollb=setInterval("wins.scrollLeft+=10",100)' onmouseout=clearInterval(scrollb)>向右</span>
<span onmouseover='scrollb=setInterval("wins.scrollTop+=10",100)' onmouseout=clearInterval(scrollb)>向下</span>
