先贴代码
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <style> .aa { border-collapse: collapse; table-layout:fixed;} .aa td { border: 1px solid #ccc; word-break:break-all; } </style></head><body> <table class="aa"> <tr> <td width="80">d</td> <td width="80">df</td> <td width="80">b</td> <td width="70">bv</td> </tr> <tr> <td>ffffffffffffffffffffffffffffffffffff</td> <td>a</td> <td>a</td> <td>a</td> </tr> </table></body></html> 第一行第一列的td宽度设置为80，按理说和它一列的td都会为80的宽度，并且也设置了自动换行 word-break:break-all;但是第二行第一列的td还是会被撑开。在IE中表现正常，我是在webkit内核的搜狗测试的，求助啊！！！
回复讨论(解决方案)
如上图所示效果，怎么没人啊 这个论坛
第二行第一列加上 width="80"
第二行第一列加上 width="80"
这个方法我知道。但是我以后做的表格很大，用jq每个td都加上width显得太冗余 ，想找其他的解决方法

css
.aa tr td:first-child{ width: 80px; } 可这个宽度不是固定的。都是我从jq循环，在页面加载的时候添加的。有什么其他解决方法
我现在只能通过jq 写 $('table tr td:nth-child(n)')的方式，挨个添加width了

宽度也动态的 你只能动态css了
我现在只能通过jq 写 $('table tr td:nth-child(n)')的方式，挨个添加width了
可以给table加上宽度，4个单元格的宽度+5个边框的宽度=315px
大致可以，但是在浏览器中查看发现宽度为314px，不太清楚怎么回事
不过这个方法应该可以解决楼主的问题
好像直接设置为0px就可以了
既然是jq控制数据，，，那就也用jq对宽度设置一下就好。。

先回复一下。我试试
我按照table的width=0测试了一下。看来是失效的。
但是通过限制总宽度这个是可行的。如图

很感谢你的方法。这应该是webkit内核的一个bug，在IE中不用加table宽度也是表现正常的。
