DW8中内容过长后撑大Table

这是小弟的代码····

<table width="420" border="0" cellspacing="4" style="table-layout: fixed; margin-top:-240px; margin-left:15px; font-size:15px; font-family: "宋体";" >
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td width="29">&nbsp;</td>
<td width="248">&nbsp;</td>
<td width="113">&nbsp;</td>
</tr>
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
<tr style="text-overflow:ellipsis; overflow: hidden; ">
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>
</table>

======================================================

请高手用CSS+DIV 帮忙修改下 或者是在什么地方用什么代码····

你的三个td根本没有吧给table的宽度用完，怎么可能不撑格

用强制换行样式,可以让内容自动换行 不会撑开!! style="table-layout: fixed;WORD-BREAK: break-all; WORD-WRAP: break-word" 宽度要设
