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;width:200;overflow:auto;background:#EEEEEE;">
<p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p>
<p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
<p>ppppppppppppppppppppppppp </p>
