Assuming every other conditions are the same, what would be the comparison of energy required to break single bond, double bond and triple bond of a carbon atom in an organic molecule?


Question: Jasper Report group subreports using columns
Answer: I think making subreports is the easiest and obvious way. But if you want to make it in other way, I can only suggest to use scriptlet, and form dataset manually (Transpose it).

Another suggestion is when you generating report directly from database (i.e. passing connection into jasper) you can modify query and transpose the data (PIVOT table). 

Anyway provide more info about your case. I will try to help you.
