The only native control you have over a table report is to group related fields next to each other. You could use script to colorize various groups of columns (not rows) according to the tab the field was in on a form. Or you could use script to layout a custom report that broke out of the blas� table layout.
Why don't you post a mockup of how you wold like your report to look irrespective of native capabilities? Let your imagination run wild and unleash yourself from reality as I am 100% confident any report format you come up with is doable with script.
