Could you give a bit more information about the dynamic nature of the report.
It appears to me that what you identify as table 1 and table 2 have the same data except for Col 5 in the table 2 presentation.
Is the intent of your report to show both tables on the same report or is there some instance where table 1 will show and other where table 2 will show? If it the later then what causes the different data to show.
I think the forum members will be better able to help if you can give us a bit more information about the report layout and data.
