Serial number in dgrid

[Mits16]

Would be a dumb question to ask, but is there a way to introduce an auto-increment column which acts as a serial number column for the records in dgrid ?
I used formatter in a column to return an incremented number, which is fine, but whenever the dgrid is sorted by clicking on headers it messes up the numbering as the first row now is not numbered 1, also I have a check box in one of the columns which triggers a method and then the dgrid again refreshes that row and the number messes up again.
Is there an easy way like assigning an auto-increment to a column which will number the rows every time the data from the memory store is read and rendered?

Do you mean you want to display row numbers?

Am I missing anything already available? Could you provide me a reference to it?
