使DIV填满整个表单元格 [英] Make a DIV fill an entire table cell

问题描述

我看过这个问题和 googled了一点儿，但没有到目前为止已经工作。我认为它现在是2010年（这些问题/答案是旧的，好，未回答），我们有CSS3！有什么方法可以使用CSS获得一个div来填充整个表格单元格的宽度和高度？

I've seen this question and googled a bit, but nothing so far has worked. I figure it's 2010 now (those questions/answers are old and, well, unanswered) and we have CSS3! Is there any way to get a div to fill an entire table cell's width and height using CSS?

我不知道单元格的宽度和/或高度将提前，并将div的宽度和高度设置为100％不起作用。

I don't know what the width and/or height of the cell will be ahead of time, and setting the div's width and height to 100% does not work.

此外，我需要div的原因是因为我需要绝对位置一些元素在单元格之外，而 position：relative 不适用于 td s，因此我需要一个wrapper div 。

Also, the reason I need the div is because I need to absolutely position some elements outside of the cell, and position: relative does not apply to tds, so I need a wrapper div.

推荐答案

以下代码适用于IE 8，IE 8的IE 7兼容模式和Chrome / p>

The following code works on IE 8, IE 8's IE 7 compatibility mode, and Chrome (not tested elsewhere):

<table style="width:100px"> <!-- Not actually necessary; just makes the example text shorter -->
   <tr><td>test</td><td>test</td></tr>
   <tr>
      <td style="padding:0;">
         <div style="height:100%; width:100%; background-color:#abc; position:relative;">
            <img style="left:90px; position:absolute;" src="../Content/Images/attachment.png"/>
            test of really long content that causes the height of the cell to increase dynamically
         </div>
      </td>
      <td>test</td>
   </tr>
</table>

您在原始问题中表示设置 width 和 height 到 100％没有工作，这使我怀疑有一些其他规则覆盖它。您是否在Chrome或Firebug中检查计算的样式，看看是否真的应用了宽度/高度规则？

You said in your original question that setting width and height to 100% didn't work, though, which makes me suspect that there is some other rule overriding it. Did you check the computed style in Chrome or Firebug to see if the width/height rules were really being applied?

我是多么的愚蠢！ div 正在调整文本大小，而不是 td 。您可以通过使 div display：inline-block 在Chrome上解决此问题，但它不适用于IE 。这证明很棘手...

How foolish I am! The div was sizing to the text, not to the td. You can fix this on Chrome by making the div display:inline-block, but it doesn't work on IE. That's proving trickier...
