How to dynamically add columns to the layout of a reporting services report

I have a query:

Select * from TableNm

The first two columns returned by the query will always be the same. However, the remaining column names and column numbers will vary everytime I run the query from tableNm table as the table structure is going to be modified every week by dropping and recreating the table.

I want to display the results of the query in a reporting services .rdl file. How can I dynamically modify/refresh the header names of the same layout in the .rdl file every time I generate the report by running the select query above. Can someone please guide me with a solution?

Thanks
