Qlik Sense - pivot table- show column if?

[katew]

Hello , 

How to hide columns with '-' values?

Maybe it is good to use 'Show column if' filed, but what formula should i put there?

Was there ever a way to not show the column if only value was '-' ?

@katew If there is no any value that is populating for those columns then I am just wondering why to add them in the Pivot table? can we just remove them?
