我想在表格单元格中使用CSS文本溢出，这样，如果文本太长而不能适合一行，它将用省略号剪辑，而不是包装到多行。这可能吗?
我试了一下:
td {
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
但是white-space: nowrap似乎使文本(及其单元格)不断向右扩展，将表的总宽度推到容器的宽度之外。但是，如果没有它，当文本到达单元格边缘时，它将继续换行为多行。

当它以表格宽度百分比为单位时，或者你不能在表格单元格上设置固定宽度。你可以应用table-layout: fixed;让它起作用。
table { table-layout: fixed; width: 100%; } td { text-overflow: ellipsis; white-space: nowrap; overflow: hidden; border: 1px solid red; } <table> <tr> <td>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</td> <td>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</td> </tr> </table>

在伸缩块中包装单元格内容。作为奖励，单元格自动匹配可见宽度。
table { width: 100%; } div.parent { display: flex; } div.child { flex: 1; width: 1px; overflow-x: hidden; text-overflow: ellipsis; } <table> <tr> <td> <div class="parent"> <div class="child"> xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx </div> <div> </td> </tr> </table>
指定max-width或固定宽度并不适用于所有情况，表应该是流动的，并自动为单元格设置空间。这就是桌子的作用。适用于IE9和其他浏览器。
使用这个:http://jsfiddle.net/maruxa1j/
table { width: 100%; } .first { width: 50%; } .ellipsis { position: relative; } .ellipsis:before { content: ' '; visibility: hidden; } .ellipsis span { position: absolute; left: 0; right: 0; white-space: nowrap; overflow: hidden; text-overflow: ellipsis; } <table border="1"> <thead> <tr> <th>Header 1</th> <th>Header 2</th> <th>Header 3</th> <th>Header 4</th> </tr> </thead> <tbody> <tr> <td class="ellipsis first"><span>This Text Overflows and is too large for its cell.</span></td> <td class="ellipsis"><span>This Text Overflows and is too large for its cell.</span></td> <td class="ellipsis"><span>This Text Overflows and is too large for its cell.</span></td> <td class="ellipsis"><span>This Text Overflows and is too large for its cell.</span></td> </tr> </tbody> </table>
如果你指定table-layout: fixed;在table元素上，那么td的样式应该生效。不过，这也会影响细胞的大小。

在我的情况下，这是有效的，在Firefox和Chrome:
td {
max-width: 0;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
width: 100%;
}
