Answer 1

This answer works only for matrixed (varied count) columns. But in all reports client want to group report data dynamicly and select column that one want to see. So if I have matrix for example with columns -

[Store] [Good] [Amount Jan] [Amount Feb].... [Amount Dec]

I can hide any column with Amount but If I right click on column Store - No option in menu- Column properties and option Column Visibility - Disabled. If apply visibility to cells - you'll see a blank space.
