export heading row by query

[yakovcohen4]

I create an excel file with export.

With the map function, I define which fields I want to return based on the data I received. (there are fields I will not show).

My question is
If I can tell the heading function that does not receive any parameter, not to display the head for a line that I do not display?

I tell the map function doesn't show me the fields...
so I dont need heading for the fields ..
