I found that extra space around a table widget sometimes appears just to
leave room for possible inclusion of scroll bars. Try to turn on scroll
bars (/SCROLL keyword to widget_table). Same with text widgets. (My IDL
is run on X-Win, MAc and PC, versions 5.1-5.2)

I'm not great fan of the table widget, so you shouldn't
consider me an expert on the subject by any means. But
when I ran your little example on my Windows NT machine
I find no excess space around the widget at all.
What machine are you running this on?
Cheers,
David
