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

这个问题在谷歌的顶部弹出，所以在我的例子中，我使用了css代码片段 从https://css-tricks.com/snippets/css/truncate-string-with-ellipsis/，但应用到td没有给出预期的结果。

我不得不在td的文本周围添加一个div标签，省略号终于起作用了。

简写HTML代码;

<table style="width:100%">
 <tr>
    <td><div class='truncate'>Some Long Text Here</div></td>
 </tr>
</table>

缩写CSS;

.truncate { width: 300px; white-space:nowrap; overflow:hidden; text-overflow:ellipsis; }

检查“nowrap”是否在一定程度上解决了问题。注意:HTML5不支持nowrap

<table border="1" style="width: 100%; white-space: nowrap; table-layout: fixed;">
<tr>
    <td style="overflow: hidden; text-overflow: ellipsis;" nowrap >This cells has more content  </td>
    <td style="overflow: hidden; text-overflow: ellipsis;" nowrap >Less content here has more content</td>
</tr>

有一个更简单、更优雅的解决方案。

在你想要应用截断的表格单元格中，只需包含一个带有css table-layout: fixed的容器div。这个容器获取父表单元格的全部宽度，因此它甚至可以响应。

确保对表中的元素应用截断。

工作在IE8+

<table>
  <tr>
    <td>
     <div class="truncate">
       <h1 class="truncated">I'm getting truncated because I'm way too long to fit</h1>
     </div>
    </td>
    <td class="some-width">
       I'm just text
    </td>
  </tr>
</table>

和css:

    .truncate {
      display: table;
      table-layout: fixed;
      width: 100%;
    }

    h1.truncated {
      overflow-x: hidden;
      text-overflow: ellipsis;
      white-space: nowrap;
    }

这是一个工作提琴 https://jsfiddle.net/d0xhz8tb/

<table style="table-layout: fixed; max-width: 100%;">
    <tr>
        <td>
             <div style="overflow: hidden; text-overflow: ellipsis; white-space: nowrap">This cells has more content</div>
        </td>
        <td>Less content here</td>
    </tr>
</table>
