Add numeration to table

Hello.
Whats the easiest way to add a column with a numeration to my table?
I want the users to have an easier life finding on which row they are
talking.
I preffer of course doing it in reporting service and not adding a
column in my dataset.
Thanks.add a text box with an expression displaying the rownumber from the Common
Functions, Miscellaneous grouping
