非JavaScript高手不可：如何实现网页的分割条？
一个三行的表格如下：

HTML code


<table width="100%" border="0">
  <tr> 
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
  </tr>
</table>

如何用JS实现将中间一行做成分割条，可上下地调整上面表格和下面表格两个表格的大小？

------解决方案--------------------
border-left:1px solid black;border-right:1px solid black;

改成
border-top:1px solid black;
border-bottom:1px solid black;

不就得了

HTML code


<TITLE> 分隔条 </TITLE>
<script language="javascript">
