Using ArcGIS 10 SP4 and used the add table to layout option. This is all within ArcGIS, this is not an external table. When exporting to PDF within ArcMap, the grid lines in the table do not print. I've searched archived forum and found a post, but this issue was not resolved. I can export to PDF or print natively without issue. I do not have full acrobat but do understand that if I used the Acrobat printer, it would render the PDF correctly. Looking for the check box that makes this work.
