It works the same as other wiki tables. The only difference is if you are using classes, you need to register them in vault/special_class_table.php using the hook there. Until you do this, most values of the class parameter will be ignored.
Also keep in mind that using a table under vBulletin 4 may inherit some rules you don't like, and because of current issues with vB, they may not render as expected in some browsers.
