css - Make a DIV fill an entire table cell

Question

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?

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.

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.

Answer 1

div height=100% in table cell will work only when table has height attribute itself.

<table border="1" style="height:300px; width: 100px;">
 <tr><td>cell1</td><td>cell2</td></tr>
 <tr>
   <td style="height: 100%">
     <div style="height: 100%; width: 100%; background-color:pink;"></div>
   </td>
   <td>long text long text long text long text long text long text</td>
 </tr>
