我有一些HTML表格以相当专业的方式布局，例如：
几乎所有关于此布局的内容都在Chrome（v48.0.2564.97 m）中完美运行。但是，Firefox（Win 7x64上的v43.0.4）搞砸了表的布局，导致最后一列太窄。
相关的CSS是：
tr > *:nth-child(1) { }
tr > *:nth-child(2) { width:30% }
tr > *:nth-child(3) { width:4em }
......第三列最终为10px宽而不是4em。
* { box-sizing:border-box}
#queues {
position:fixed; top:0; left:0; right:0; bottom:0;
overflow:hidden;
display:flex;
flex-direction:row;
justify-content:space-between;
align-items:flex-start;
}
table {
display:flex;
flex-flow:column;
height:100%; width:33%;
margin-right:4px;
overflow:hidden;
border-collapse:collapse;
}
table:last-child { margin-right:0 }
/* head takes the height it requires, and it's not scaled when table is resized */
table thead { flex:0 0 auto; width:calc(100% + 1px) }
/* body takes all the remaining available space */
table tbody { flex:1 1 auto; display:block; overflow-y:auto }
table tbody tr { width:100% }
table thead,
table tbody tr { display:table; table-layout:fixed }
td { max-width:0; overflow:hidden; white-space:nowrap; text-overflow:ellipsis }
tr > *:nth-child(1) { }
tr > *:nth-child(2) { width:30% }
tr > *:nth-child(3) { width:4em; text-align:right }
th { text-align:left; background:#ccc; color:rgba(0,0,0,0.4) }

这里的Firefox错了吗？更重要的是，如何修复它以使最后一列保持固定宽度（同时保留上面的特征1-4）？
同样在JSFiddle上：https://jsfiddle.net/y4p93kmn/1/
答案 0 :(得分：1)
当然，在我写完问题并削减代码之后，我找到了解决方案。
出于某种原因，它修复了Firefox在第三列添加min-width:4em和width:4em的问题。
tr > *:nth-child(1) { }
tr > *:nth-child(2) { width:30% }
tr > *:nth-child(3) { width:4em; min-width:4em }
