Row and cell color in print output

[Zbyszek Cybulski <z.cybulski@gmail.com>]

Hi,

I want some table cells to have colored background. If I set the
<?dbfo bgcolor="yellow" ?> processing instruction for a table row
(after <row>), the print output shows a yellow row in a table.
But when I do it for a cell (after <entry>), it doesn't work and
the cell has no yellow background in PDF. 
I use XEP 4.3 with DocBook 4.4 and XSL 1.68.1 on Windows.

Anyone can help?

Thanks,
-Z
