td对应问题

[cattle13]

今天在做页面的时候遇到的一个问题.
先看一段代码:
<script language=javascript>
function settab(m){
m.style.display=(m.style.display=="none")?"block":"none";
}
</script>
<table width="650" border="0" cellpadding="0" cellspacing="4" dataPageSize="20" id="table" DATASRC='#xmlfso'>
<tr height="25" style="cursor:pointer;" onclick="settab(this.childNodes[3])">
<td width="130" height="12" align="left"><span datafld="分类" /></td>
<td width="130" align="left"><span datafld="标准" /></td>
<td width="180" align="left"><span datafld="标题" /></td>
<td align="left" bgcolor="#f0f0f0" style="display:none;">　　<span datafld="内容" /></td>
</tr>
</table>
这个是我导入xml的表格,现在能实现点击每一行,内容能自动显隐,但在右边.
如果我想内容显示下面改怎么办?
表格如下
<script language=javascript>
function settab(m){
?
}
</script>
<table width="650" border="0" cellpadding="0" cellspacing="4" dataPageSize="20" id="table" DATASRC='#xmlfso'>
<tr height="25" style="cursor:pointer;" onclick="settab(?)">
<td width="130" height="12" align="left"><span datafld="分类" /></td>
<td width="130" align="left"><span datafld="标准" /></td>
<td width="180" align="left"><span datafld="标题" /></td>
</tr>
<tr>
<td align="left" bgcolor="#f0f0f0" style="display:none;">　　<span datafld="内容" /></td>
</tr>
</table>

有办法实现吗?

有，当然有

[jsjhuage]

<script language=javascript>
function settab(obj){
table.rows[obj.rowIndex+1].style.display=(table.rows[obj.rowIndex+1].style.display=="none")?"block":"none";
}
</script>
<table width="650" border="0" cellpadding="0" cellspacing="4" dataPageSize="20" id="table" DATASRC='#xmlfso'>
<tr height="25" style="cursor:pointer;" onclick="settab(this)">
<td width="130" height="12" align="left"> <span datafld="分类" /> </td>
<td width="130" align="left"> <span datafld="标准" /> </td>
<td width="180" align="left"> <span datafld="标题" /> </td>
</tr>
<tr>
<td align="left" bgcolor="#f0f0f0" style="display:none;"> 　　 <span datafld="内容" /> </td>
</tr>
</table>
是不是要这样呢？

<script language=javascript>
function settab(m){
m.style.display=(m.style.display=="none")?"":"none";
}
</script>
<tr height="25" style="cursor:pointer;" onclick="settab(this.nextSibling.childNodes[0])">
