这样的一个表格如何隐藏显示指定的行,麻烦大家了..
<table width= "300 " border= "2 " cellspacing= "0 " cellpadding= "0 ">
<tr>
<td width= "100 "> a </td>
<td width= "100 "> 1 </td>
<td width= "100 "> 显示 </td>
</tr>
<tr>
<td width= "100 "> a </td>
<td width= "100 "> 2 </td>
<td width= "100 "> </td>
</tr>
<tr>
<td width= "100 "> a </td>
<td width= "100 "> 2 </td>
<td width= "100 "> </td>
</tr>
<tr>
<td width= "100 "> b </td>
<td width= "100 "> 1 </td>
<td width= "100 "> 显示 </td>
</tr>
<tr>
<td width= "100 "> b </td>
<td width= "100 "> 2 </td>
<td width= "100 "> </td>
</tr>
<tr>
<td width= "100 "> c </td>
<td width= "100 "> 1 </td>
<td width= "100 "> 显示 </td>
</tr>
<tr>
<td width= "100 "> c </td>
<td width= "100 "> 2 </td>
<td width= "100 "> </td>
</tr>
<tr>
<td width= "100 "> c </td>
<td width= "100 "> 2 </td>
<td width= "100 "> </td>
</tr>
</table>
我要的效果是点击a和1旁边的显示时则显示所有a和2的行,再点击一下则隐藏有a和2的行,点有b和1旁边的显示时则显示所有b和2的行,再点击一下则隐藏有b和2的行
