Adding a new column in ascending order

[missteran]

How can I create a new column where the row counts in ascending order? counting from 1 through whatever number the final row falls?

Goal "New Column" :

ID	New Column
688654154	1
3548787454	2
478784	3
6468787	4
87987418	5
54867654	6
54874845	7
5456454	8
4874663	9
232635695	10
546411545	11
1315645412	12
51451524	13
5145478547	14
696463213	15
