this is because tbl is using characters to draw lines.
it's not a great strategy.

maybe should be doesn't.  there's a reason no one uses it.
even if it worked, boxes around words are pretty heavy weight.

you can start page with a ppi parameter: page -p 150 file.ps
i have never managed to get gs to let me change that parameter

and then make zoom on postscript files use that mechanism.
