Put a box around one td element?

[runner]

Is there a way to put a box around one single td element in a table? I'm making a table-based calendar and I want to have a box around the current day.

If I can't do this I'll have to go to plan B and change the background color of that one td element.

This seems to do the trick.

<table> 
<tr> 
<td>1</td> 
<td>2</td> 
<td>3</td> 
</tr> 
<tr> 
<td>4</td> 
<td style="border: thin solid black">5</td> 
<td>6</td> 
</tr> 
<tr> 
<td>7</td> 
<td>8</td> 
<td>9</td> 
</tr> 
</table>

Works great! Thanks...
