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();

修复了jsfiddle的IE兼容性问题。 修复jsfiddle中更好的浏览器兼容性(Chrome, Firefox, IE8+)。

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.

几天前我也遇到了同样的挑战。看来路西法·萨姆找到了最好的解决办法。

但我注意到你应该在spacer元素复制内容。认为它不是那么糟糕，但我也想应用标题弹出剪切文本。这意味着长文本将在我的代码中出现第三次。

在这里，我建议在伪元素之后访问title属性以生成间隔并保持HTML干净。

适用于IE8+， FF, Chrome, Safari, Opera

<table border="1">
  <tr>
    <td class="ellipsis_cell">
      <div title="This cells has more content">
        <span>This cells has more content</span>
      </div>
    </td>
    <td class="nowrap">Less content here</td>
  </tr>
</table>

.ellipsis_cell > div {
    position: relative;
    overflow: hidden;
    height: 1em;
}

/* visible content */
.ellipsis_cell > div > span {
    display: block;
    position: absolute; 
    max-width: 100%;
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
    line-height: 1em;
}

/* spacer content */
.ellipsis_cell > div:after {
    content: attr(title);
    overflow: hidden;
    height: 0;
    display: block;
}

你可以试着“加权”某些列，像这样:

<table border="1" style="width: 100%;">
    <colgroup>
        <col width="80%" />
        <col width="20%" />
    </colgroup>
    <tr>
        <td>This cell has more content.</td>
        <td>Less content here.</td>
    </tr>
</table>

您还可以尝试一些更有趣的调整，如使用0%宽度的列和使用一些组合的白色空间CSS属性。

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

你懂的。

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; }

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?
