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>

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.

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);
        }
    });
});

我相信我有一个非javascript的解决方案!我不想满足于JavaScript的修复，因为我发现页面加载后东西移动的轻微抖动是不可接受的。

特点:

没有JavaScript 没有固定布局 没有加权或百分比宽度技巧 适用于任意数量的列 简单的服务器端生成和客户端更新(不需要计算) 跨浏览器兼容的

How it works: Inside the table cell place two copies of the content in two different elements within a relatively-positioned container element. The spacer element is statically-positioned and as such will affect the width of the table cells. By allowing the contents of the spacer cell to wrap we can get the "best-fit" width of the table cells that we are looking for. This also allows us to use the absolutely-positioned element to restrict the width of the visible content to that of the relatively-positioned parent.

测试和工作在:IE8, IE9, IE10, Chrome, Firefox, Safari, Opera

示例HTML / CSS:

<td>
    <!--Relative-positioned container-->
    <div class="container">
        <!--Visible-->
        <div class="content"><!--Content here--></div>
        <!--Hidden spacer-->
        <div class="spacer"><!--Content here--></div>
        <!--Keeps the container from collapsing without
            having to specify a height-->
        <span>&nbsp;</span>
     </div>
</td>

.container {
    position: relative;
}
.content {
    position: absolute;
    max-width: 100%;
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}
.spacer {
    height: 0;
    overflow: hidden;
}
