Table row colors

[slomium]

Hi,

How do I color a row in a table a color other than one 
of the standard ones.

for instance

bpaint{0.7 0.7 0.7 setcolor}

doesn't get me anywhere.  All I've managed to do, so 
far, is generate invalid postscript or no color change.  
I haven't managed to get any error messages from lout, 
though.

Thanks,
Dave
