回答1:
You can't really suppress horizontal space in the same way you can suppress vertical space (via the suppression of report sections, etc.). So, while you could technically suppress that column's fields, header, lines, etc. with the suppression formula max({table.PicksUpsCRY})>0, you won't be able to get rid of the whitespace and it'll appear as though you've just got a hole in your table.
You could move this column to the end so it's not as obvious that there is a column missing, though.
