[SOLVED] Unable to center table on page

Working on table that contains images at http://www.mysweetmocha.com/manual-c...ahead-of-time/

I followed instructions found in this forum but table does not center on page.

html on page:
<div id="table1">
</div>

css insert
#table1 {
margin-left: 03% ;
margin-right: auto;
}

I did try auto instead of 03% - not work. Thank you for any assistance.
