Custom Ruling & Shading

[Lin Sims]

(As an aside -- wow! it's been a long time since I've been on this
list. I'm glad to be back at a gig where I get to use Frame!)

I'd like to set up a single cell table that sort-of mimics the look of
a terminal window. What I'd like is to have a double border, outside
medium width, darkish grey, inside thin, lighter grey. Is that even
possible? Help isn't being helpful.

Thanks.
