I like to create text columns above the expressions I have grouping them together with "Super headers". Just like in Excel you can merge cells...
Pivot table is not an option I suppose because I've up to 5 groups of columns with each 2 to 3 columns(expressions)
| Turnover | Productivity |
| Week | YTD | MTD | Hours | Value |
City | | | | | |
a | |
Thx in advance for your suggestions!!
