How to pass value in rows to another column

[julian_ortiz]

Hi, i have this data

Month	Value
201205	200
201204	100
201203	50
201202	100

I want manipulate the data and pass to one row, like this

Month	Current	Month-1	Month-2
201205	200	100	50
201204	100	50	100
201203	50	100	0

The idea is have the current value and the last 4 months.

¿Any suggestions?

Thanks in advance

Julian
