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;
}

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。

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();

我有同样的问题，但我需要显示多行(其中text-overflow:省略号;失败)。我解决它使用一个TD内的文本区域，然后样式它的行为像一个表格单元格。

    textarea {
        margin: 0;
        padding: 0;
        width: 100%;
        border: none;
        resize: none;

        /* Remove blinking cursor (text caret) */
        color: transparent;
        display: inline-block;
        text-shadow: 0 0 0 black; /* text color is set to transparent so use text shadow to draw the text */
        &:focus {
            outline: none;
        }
    }

如果Javascript是可以接受的，我把一个快速例程放在一起，你可以作为一个起点。它动态地尝试使用跨度的内部宽度来适应单元格宽度，以响应窗口调整大小事件。

目前，它假设每个单元格通常获得行宽的50%，并且它将折叠右侧单元格以保持左侧单元格的最大宽度，以避免溢出。您可以实现更复杂的宽度平衡逻辑，这取决于您的用例。希望这能有所帮助:

我用于测试的行标记:

<tr class="row">
    <td style="overflow: hidden; text-overflow: ellipsis">
    <span>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</span>
    </td>
    <td style="overflow: hidden; text-overflow: ellipsis">
    <span>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</span>
    </td>
</tr>

JQuery，它连接了resize事件:

$(window).resize(function() {
    $('.row').each(function() {
        var row_width = $(this).width();
        var cols = $(this).find('td');
        var left = cols[0];
        var lcell_width = $(left).width();
        var lspan_width = $(left).find('span').width();
        var right = cols[1];
        var rcell_width = $(right).width();
        var rspan_width = $(right).find('span').width();

        if (lcell_width < lspan_width) {
            $(left).width(row_width - rcell_width);
        } else if (rcell_width > rspan_width) {
            $(left).width(row_width / 2);
        }
    });
});
