This works for tabular indent as well:
CODE
<!--
/* change these numbers and make them add up to 100 or less*/
table {
width: 50%;
margin-left: 25%;
margin-right: 25%;
}
/* don't change these numbers */
table table {
width: auto;
margin:0;
}
table table table {
width: 0;
}
-->
And you can change the percentages to pixel values if you want. :)
