Well, a button is a bit more complicated, but you could use a link if that's okay for you.
You make the column and then make it a link (under column settings in report settings), submitting the page and using some Request (e.g. EXECUTE_PROC).
Then you make a process (after submit or after validiations depending on your goal) where you call the stored procedure.
To get the input parameter you can do the following:
1. make a hidden item
2. when you submit the page you can assign the value of the column to the item
3. use the item in the process when calling the procedure.
This is just a short description - I'm quite confident, that you will be able to do it with those informations and probably a little reading in the documentation.
