[Pharo-project] CSS style for tables in http://book.pharo-project.org/

Hi (Doru?) I was just creating this page: http://book.pharo-project.org/book/TipsAndTricks/InterruptKey and seems there is no style for table, tr, td, etc. I checked with firebug and the html is correct. So I guess we could add style. I tried to go to the css component and check but it seems I don't have access. But that's better because I am horrible with css ;) Now I wonder...can we put style to tables? at least border ;) Maybe I did something wrong. Thanks mariano
