I cannot get this style to work. Take a look at my drawing:

Markup:
<h1Title</h1>
<table>
<tr>
<td>
<dfn>help</dfn>
<a href="link0.php">
<span>text</span></a>
</td>
<td><a href="link1.html">
<span>text</span></a>
</td>
</tr>
</table>
I’m trying to make the <td> element clickable by using the <a> element as a block. But, I need to put a small “header” with <dfn> element inside the <td> too. I can make the <dfn> align to top-right and preserve the <a> vertical text align relative to its container without conflicting with <dfn> when it exists.
Thank you in advance
I changed your markup bit and added some positioning and padding to get something close to the image you posted:

The borders in the demo represent the cell borders. The grey background is the link area.
