For what it's worth, I've changed the CSS that Kr33p3r provided to match the vb default theme:
Code:
.stg_table { background:url("images/buttons/newbtn_middle.png") repeat-x scroll 0 0 #7192A8; border:1px solid #E9E9E9; color:#FFFFFF; font:12px Tahoma,Calibri,Verdana,Geneva,sans-serif; padding:2px 0;}
.stg_table .alt1 { background:none repeat scroll 0 0 #F2F6F8; border-width:1px solid #E9E9E9; color:#000000 }
.stg_table .alt2 { background:none repeat scroll 0 0 #FFFFFF; border-width:1px solid #E9E9E9; color:#000000 }
I'm not a CSS guru, so there's probably unnecessary stuff there... but hey, it works for me.
