You could actually achieve this by using Dimension Limits on the straight table and just selecting Show Total on the second dimension. However even if you can do this a Pivot Table might be the best solution. Below are screen shots of this being done with a straight table.
Thank you for all your answers. They have been very helpful.
Now I have a another question. I want to sum rows (ICA 2 Ica (böcker) 4% and (ICA Ica) and call the row lets say "Ica". How do I do that? Do I have to use an Expression? (what expression in that case)or is there a aggragate box to mark?
