Hello everyone!

Can anyone please help me with this? I have multiple set of column headers. Adding another set of columns in another ‘Groupheader’ results to (1st line) COLUMN1, followed with (2nd line) DETAILS1, then (3rd line) COLUMN2, followed with (4th line) DETAILS2. I want it that COLUMN1 list down all DETAILS1 before COLUMN2 and DETAILS2 follows (just like in the picture, here, I have them in separate reports). Please help me out! Thank you!
