Center align table with CSS

[rnv]

Hi, I can simply use the following tag to horizontally align a table to center:

<table align="center" class="centertable">

I would like to use the CSS to do the same but somehow I cannot make it work. here is how i tried. Will appreciate help.

.centertable {align:center;}

with best regards,rnv

.centertable{  width: 500px;  //need to give the element some sort of width  margin: 0px auto;  //how to center a block level element, given that you have given it a width}
