A frame box with "no inner box" can be set to width="1 width" meaning
that the box will have the width of whatever it contains. This is very
nice for making double-border tables, or higlighting a word with a box.
Unfortunately, lyx seems to assume that such a box is a narrow column.
Output is ok, but the content on screen is squashed into a horrible
narrow column, whenever such a box is applied to wide content. A boxed
wide table looks _really_ bad this way. Try and cry.
Suggested fix: Don't let such a box limit the display. Draw the contents
as if
the box wasn't there, and paint the box around the result. Or a box the
width of the lyx window if that is easier. Anything but this . . .
