  Thanks Ken, that works great for the problem I described.  The
real problem, though, is a bit more complex.

Isn't that always the case! :{)}

The first three
cells (those to put the text on the background) are spanned over
several rows.  And the table cells have borders.  I've adapted
your example to reflect this situation:

    http://www.fgeorges.org/tmp/background-text-ken.fo
    http://www.fgeorges.org/tmp/background-text-ken.pdf

  You can see in the PDF that the height of the cells is not
spanned anymore over the lines.

Only because they have no knowledge in the inner table about spanning going on outside of the table ... but that is algorithmically determinable.

Ideally, what I would like is
something like this (the vertical position of the background
text does not really matter):

http://www.fgeorges.org/tmp/background-text.jpg

  But I don't know how to tell the processor to use all the
available vertical space for the inner table.

By expressing the block-container height in the cells to be the sum of the heights of the rows being spanned. I had to do this in my UN layout key stylesheets: every cell had an explicit block-progression-dimension= property.

As I said, you are limited in your heights by having to expressly calculate what the heights are for cells.

But since you know which rows are being spanned, and (hopefully) which heights are in those rows, it can still be calculated.

I hope the modified example below helps.
