numbering rows

How do i number the rows in the table? My data does not have any unique
values if that helpsThere is a RowNumber(<scope>) function, where <scope> is a string that
identifies a data region, dataset or grouping if you need that context. For
just a simple running row total, use RowNumber(Nothing). You can also use
it for visual effects, and the most frequent example of this is to create
"green bar" reports by setting the background colour of a table row with the
expression:
=iif(RowNumber(Nothing) Mod 2, "Green", "White")
