Re: Table cellspacing
I'm no html/css wiz, but I would guess you should be able to do so by creating your own css-file, adding it to the page, and then setting the correct classes in those methods.
HOW you do it in css is not something I know of the bat though. :)
Like I said, skinning/styling of components is probably one of the weaker areas currently in Wicket RAD, and could use some improvement..
