Difference between the straight table and pitvot table!
Please ask the manual or the help system - it has lots of answers for you and your questions. Also, it would help, if you were trying to learn some basics of Aggregation, Grouping and Pivot-Tables. This is very basic knowledge which isn't Qlikview-specific and everything relevant for Qlikview has been written before by Rhagu and Erika.
BTW - stop apologizing for your questions - I know you will ;-)
