简单地添加以下规则到你的td:

overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
// These ones do the trick
width: 100%;
max-width: 0;

例子:

表 { 宽度： 100% } 道明 { 空白：无换行; } .td-truncate { 溢出：隐藏; 文本溢出：省略号; 宽度： 100%; 最大宽度： 0; } <表边框=“1”> <tr> <td>内容</td> <td class=“td-truncate”>long contenttttttttt ttt</td> <td>其他内容</td> </tr> </table>

PS: 如果你想将一个自定义宽度设置为另一个td，使用属性min-width。

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

<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>

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。

<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>

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.
