如何使表格列成为最小宽度 [英] How to make a table column be a minimum width

问题描述

以下是模板数据文件：

正如您在上面的小提琴中看到的那样， nowrap 强制表格单元格以防止任何换行符，并因此将其宽度调整到尽可能最小。

注意：如果您有 thead ，您想要将 td 的样式应用于 th 。

$ hr
$ b

更新＃1：省略号（...）

<要自动将较长的列折叠为省略号， text-overflow：ellipsis 是您可能要查找的内容：

  td.cell-collapse {
 max-width：200px; 
 overflow：hidden; 
文本溢出：省略号; 
} 
  

现场演示

这也需要 overflow 设置为隐藏，以及宽度或 max-width 与一个固定值。将 cell-collapse 类添加到您想限制宽度的单元格中。

UPDATE＃2：处理引导程序

引导程序的表类集宽度：100％; 这会搞砸这个方法。你可以用 table {width：inherit！important; }

现场演示注意：此方法中的表已经具有全宽，因为表单元格已经具有 width：auto;

先前基于Javascript的解决方案已被删除，所有现代浏览器。链接的 JSfiddle 中仍有原始代码，已注释。

Here is the template data file: https://github.com/Hoektronics/BotQueue/blob/master/views/bot/dashboard_list.ejs

I'm trying to make 8 of the 10 columns of a table to only take up exactly the minimum width that they need to, based on the text, respecting the padding and column headers.

In the example image, I want all but the 4th and 9th columns to take up the minimum width. Technically, there are 9 column headers, and the last one has a colspan of 2. The last header is a span3. I'd like the percentage column to take up the least width that is needed, and let the progress bar or the pass/view/fail buttons take up the rest.

Column 4 is set up to replace overflowed text with an ellipsis.

解决方案

There is a trick that involves setting some cells to a very small width, and then applying a white-space: nowrap property:

<table>
    <tr>
        <td class="min">id</td>
        <td class="min">tiny</td>
        <td>Fills space</td>
        <td>Fills space</td>
        <td class="min">123</td>
        <td class="min">small</td>
        <td>Fills space, wider</td>
        <td>Fills space</td>
        <td class="min">thin</td>
    </tr>
</table>

td {
    width: auto;
}

td.min {
    width: 1%;
    white-space: nowrap;
}

Live demo

As you can also see in the above fiddle, nowrap forces the table cell to prevent any line-breaks, and thus align its width to the smallest possible.

NOTE: If you have a thead, you want to apply the td's stylings to th as well.

UPDATE #1: Ellipsis (...)

To automatically collapse a longer column into ellipses, the text-overflow: ellipsis is what you are likely looking for:

td.cell-collapse {
    max-width: 200px;
    overflow: hidden;
    text-overflow: ellipsis;
}

Live demo

This also requires overflow set to hidden, as well as a width or max-width with a fixed value. Add the cell-collapse class to cells whose width you would like to limit.

---

UPDATE #2: Handling Bootstrap

Bootstrap's table class sets width: 100%; which will mess up this approach. You can fix that with table { width: inherit !important; }

Live demo

NOTE: The tables in this approach already have full width because table cells already have width: auto;.

Previous Javascript-base solution removed, since the pure CSS-based approach now works consistently across all modern browsers. The original code is still available at the linked JSfiddle, commented out.
