CSS Table won't center

[Rainyplace]

hi all,

I have done some searching on google and can't find a code to center my css table in my products description that actually works. It will only align left.

Here is my code.. maybe i'm missing something.

Cheers,
Grant.

<style type="text/css">
table.stats
table { margin: auto; }
{text-align: center;
font-family: Verdana, Geneva, Arial, Helvetica, sans-serif ;
font-weight: normal;
font-size: 10px;
color: #fff;
width: 500px;
background-color: #666;
border: 0px;
border-collapse: collapse;
border-spacing: 0px;}

table.stats td
{background-color: #eeeeee;
color: #000;
padding: 4px;
text-align: left;
border: 1px #fff solid;}


table.stats td.hed
{background-color: #e8e9e9;
color: #000000;
padding: 4px;
text-align: center;
border-bottom: 2px #fff solid;
font-size: 12px;
font-weight: bold;} 
</style>
