关键是外面的<table>不能强制设置宽度和高度，用百分比设也不行，外面的<table>可以根据字符多少自动变化，内部的<table>也要随之撑大充满<td>

[wuyue-tiger]

up

[linhahn]

将内部的table<table width=100%>

[wuyue-tiger]

主要是高度上要充满，写成height=100%是没用的啊

[wangmingsky]

height=100% 写在tr里

[wuyue-tiger]

是这样一个结构，前一个td可能把这一行撑得很高，但右侧的table不会改变大小去充满自已的那个td
<table>
<tr>
<td>a<br>a<br>a<br>a<br>a<br>a<br></td>
<td>
<table><tr><td>aaaaaaa</td></tr></table>
</td>
</tr>
