奇怪的1像素间距 =。=
一个三行的表格，把中间的那行设成display:none，上下两行没有并拢，而是留了一个像素的间距，求解
代码如下:
-----------------------------------
<table border= "0 " cellspacing= "0 " cellpadding= "0 ">
<tr>
<td width= "164 " style= "background: #FF0000; width: 100px; height: 30px; "> </td>
</tr>
<tr>
<td style= "background: #00ff00; display: none; width: 100px; height: 30px; "> </td>
</tr>
<tr>
<td style= "background: #FF0000; width: 100px; height: 30px; "> </td>
</tr>
</table>
[解决办法]
<table border= "0 " cellspacing= "0 " cellpadding= "0 ">
<tr>
<td width= "164 " style= "background: #FF0000; width: 100px; height: 30px; "> </td>
</tr>
<tr style= "display: none; ">
<td style= "background: #00ff00; width: 100px; height: 30px; "> </td>
</tr>
<tr>
<td style= "background: #FF0000; width: 100px; height: 30px; "> </td>
</tr>
</table>
