layout within <td>

How can I get the following to appear on just 1 line?

<style type="text/css">
#center { text-align: center;}
#left { text-align: left;}
#right {text-align: right}
</style>

<table border=1 width=200>
<tr>
<td>
<div id="left">left
<div id="center">center
<div id="right">right
</td>
</tr>
</table>

I tried using "display:inline" and play with "float" property but
couldn't get it to work right.
Thanks!

Thanks for your help! Not closing the <div> elements was my mistake
(sorry). Putting everything in 3 different table cells that's
unfortunately is not an option. I'd also want to stay away from
hardcoding the pixel sizes. I'd be happy with the output that I'm
getting in my original example if everything was simply on 1 line (I
though that's what "display:inline" was supposed to do but that doesn't
seem to be the case).
