Column Data as a Column Header in SSRS 2012

I want to use the column data as a column header in the SSRS report. I am using the column data as a column group while creating the SSRS report. But depending on the filter conditions, the header columns changes dynamically. How can we make it static?

For eg.

Supplier         Flow    Amount       

======      =====  ========

A                  Adhoc       20

A                  Pay          30

B                 Adhoc        15

So when I select the Supplier A as a parameter, report output is

Supplier            Adhoc                     Pay

A                        20                         30

but when I select the supplier B as  a parameter, report output is

Supplier            Adhoc

B                          15

What I want when supplier B is selected, report output should be

Supplier         Adhoc                     Pay

B                     15
