我有 2 个表格，一个叠在另一个上面，我想将它们的列宽完全对齐，有没有办法做到这一点？尝试过固定表格列宽度等没有任何乐趣

你可以看到 fiddle 上的列彼此稍微偏离 http://jsfiddle.net/askhe/

table.tblresults {
    width:100%;
    *width:99.5%;
    border: 1px solid #b9b8b8;
    top: 0;
}
table.tblresults tr.tblresultshdr {background: lightgrey;}
table.tblresults tr.tblresultshdr td {padding: 6px;}
table.tblresults td {padding: 8px; border: 1px solid #b9b8b8;}
table.tblresults td.col1 {width: 70%;}

最佳答案

table 用于科学数据的元素，例如来自实验的探针，而不是用于实际布局:

Tables should not be used purely as a means to layout document content as this may present problems when rendering to non-visual media. Additionally, when used with graphics, these tables may force users to scroll horizontally to view a table designed on a system with a larger display. To minimize these problems, authors should use style sheets to control layout rather than tables.

虽然您没有将它们用于布局，但您的问题实际上是渲染/布局问题。最简单的解决方案是 merge both tables into one (jsfiddle) .

如果您希望将数据封装在许多小表格中而不是一个大表格中，您需要为几乎所有列指定宽度。
