To change the column Headers dynamically in table visual

Hi All,
I'm trying to change the column headers dynamically in the table visual.
I have a lot of columns like the normal ones... Some are the columns that contain the label name, which changes dynamically through BusinessId.

For example :

In the place of (Headers) FirstValueA , SecondValueB, ThirdValueC,  and FourthValueD, 

the values that are contained under Custom Label A,B, C, and D should change accordingly to the businessId

Expected Output:
for BusinessId 1

For BusinessId 2

For BusinessId 3

and if none of the business IDs are selected, the header should display CustomLabel 1, CustomLabel 2, CustomLabel 3, and CustomLabel 4 for those fields. 
I tried using unpivot but couldn't achieve the expected output. 

Any help would be much appreciated. 
Thank You!
