ff下table标签行与行间出现缝隙，ie不会

Question

css中

img  {border:none;} 
.right_lan_ff { 
    height:35px;    vertical-align:middle;    text-align:center; 
    background-image:url(../images/lanmu_bak.gif); 
    line-height:42px;    cursor:pointer;    margin-bottom:2px; } 

程序：

.......

<div id="item2" class="right_lan_ff" onclick="onExpandItem(this,'lay2');"> 云台控制<img id="imgitem2" src="images/index-5.gif"/></div> 
  <div id="lay2" > 
    <div> 
      <table align="center"    cellpadding="0" cellspacing="0" height="134" style="border-collapse:collapse;"> 
        <tr  align="center" heigh="37" width="133" cellpadding="0" cellspacing="0" > 
          <td align="center" heigh="37" width="37" cellpadding="0" cellspacing="0" ><img src="images/html_26a.gif" width="37" height="37" /></td> 
        </tr> 
        <tr  align="center" heigh="57" width="133" cellpadding="0" cellspacing="0" > 
          <td align="center" heigh="57" width="37" cellpadding="0" cellspacing="0" ><img src="images/html_30a.gif" width="37" height="57" onmousedown="PTZControlCmd('LEFT', 0);" onmouseup="PTZControlCmd('LEFT', 1);"/></td> 
        </tr> 
        <tr  align="center" heigh="40" width="133" cellpadding="0" cellspacing="0" > 
         <td align="center" heigh="40" width="37" cellpadding="0" cellspacing="0" ><img src="images/html_33a.gif" width="37" height="40" /></td> 
       </tr> 
      </table> 
   </div> 

.....

ie中能正常显示，ff中table标签行（img）之间有一条缝隙，该如何解决？

Answer 1

css使用

table{border-collapse: collapse; border-spacing: 0;}

Answer 2

改用ur li做吧，比table省心。

Answer 3

二者是有区别的，太正常了，尽量少用 table 吧
