In Excel tables, I can keep entries or certain columns of an entry blank "". This helps me locate incomplete or work-in-progress items.
But since CDM validates the data according to values, text, etc., I am not able to achieve blank records. By default, columns that are numbers fill in a 0 when I try to make a blank. I see 0 and blank as two different situations, which is very beneficial to formulas overall. When I want a blank to be zero, that can be done with Value(), Len() or any other creative solution, so it's more flexible to allow blanks.
