Yep I would say thirtydot has it, there is no way to do it unless you use a js method. You are talking about a complex set of rendering conditions that you will have to define. e.g. what happens when both cells are getting too big for their apartments you will have to decide who has priority or simply just give them a percentage of the area and if they are overfull they will both take up that area and only if one has whitespace will you stretch your legs in the other cell, either way there is no way to do it with css. Although there are some pretty funky things people do with css that I have not thought of. I really doubt you can do this though.

你可以设置右边单元格的宽度为所需宽度的最小值，然后应用overflow-hidden+text-overflow到左边单元格的内部，但是Firefox在这里有bug…

不过，flexbox似乎能帮上忙

我最近一直在研究它。检查这个jsFiddle测试，自己尝试改变基本表的宽度来检查行为)。

解决方案是将一个表嵌入到另一个表中:

<table style="width: 200px;border:0;border-collapse:collapse">
    <tbody>
        <tr>
            <td style="width: 100%;">
                <table style="width: 100%;border:0;border-collapse:collapse">
                    <tbody>
                        <tr>
                            <td>
                                <div style="position: relative;overflow:hidden">
                                    <p>&nbsp;</p>
                                    <p style="overflow:hidden;text-overflow: ellipsis;position: absolute; top: 0pt; left: 0pt;width:100%">This cells has more content</p>
                                </div>
                            </td>
                        </tr>
                    </tbody>
                </table>
            </td>
            <td style="white-space:nowrap">Less content here</td>
        </tr>
    </tbody>
</table>

Fred现在对Celldito的扩张满意吗?

<table border="1" style="width: 100%;">
    <colgroup>
        <col width="100%" />
        <col width="0%" />
    </colgroup>
    <tr>
        <td style="white-space: nowrap; text-overflow:ellipsis; overflow: hidden; max-width:1px;">This cell has more content.This cell has more content.This cell has more content.This cell has more content.This cell has more content.This cell has more content.</td>
        <td style="white-space: nowrap;">Less content here.</td>
    </tr>
</table>

假定“表布局:固定”是基本的布局要求，这将创建均匀间隔的不可调整列，但您需要使单元格的百分比宽度不同，也许设置单元格的“colspan”为倍数?

例如，为了方便百分比计算，使用总宽度为100，并且假设您需要一个单元格为80%，另一个单元格为20%，考虑:

<TABLE width=100% style="table-layout:fixed;white-space:nowrap;overflow:hidden;">
     <tr>
          <td colspan=100>
               text across entire width of table
          </td>
     <tr>
          <td colspan=80>
               text in lefthand bigger cell
          </td>
          <td colspan=20>
               text in righthand smaller cell
          </td>
</TABLE>

当然，对于80%和20%的列，您可以将100%宽度的单元格colspan设置为5,80%宽度的单元格colspan设置为4,20%宽度的单元格colspan设置为1。

就像samplebias答案一样，如果Javascript是一个可接受的答案，我专门为此目的做了一个jQuery插件:https://github.com/marcogrcr/jquery-tableoverflow

要使用插件，只需输入

$('selector').tableoverflow();
