Wikitable

Add the following to : http://ubi.cs.washington.edu/wiki/index.php/MediaWiki:Common.css <css> /* wikitable/prettytable class for skinning normal tables */

table.wikitable, table.prettytable {

 margin: 1em 1em 1em 0;
 background: #f9f9f9;
 border: 1px #aaa solid;
 border-collapse: collapse;

}

table.wikitable th, table.wikitable td, table.prettytable th, table.prettytable td {

 border: 1px #aaa solid;
 padding: 0.2em;

}

table.wikitable th, table.prettytable th {

 background: #f2f2f2;
 text-align: center;

}

table.wikitable caption, table.prettytable caption {

 margin-left: inherit;
 margin-right: inherit;
 font-weight: bold;

} </css>

This style allows you to create nice looking tables like so:
