Hi,
The best style for this type of report is the JOURNAL style...it has only black and white output and no interior table lines.
For examples of performing other cosmetic changes with Proc REPORT you should search LexJansen.com for Pharmasug papers on the creation of clinical reports. In addition, my SGF paper, "Creating Complex Reports" had several different examples of this type of report.
And you may find that someone at your company already has produced a similar report, if you investigate.
