I have a table of events and their income and expenses.  Each line shows only one amount (like a checkbook register) so there are multiples per event and I would like to create a table with one line per event with one column showing the total income and the next column showing the total expense, with the final column showing the grand total profit or loss.  How do I go about creating a calculation for this?
