[Feat] Column with Auto numbering

[jcasement]

@IvanJosipovic Maybe this is already in the wish list but the reason I'm asking for this is to put to use a CustomRow in row 0. Always!
This would act like a sticky header so that row zero on every page would have this header.
I see in the example the every fourth row has the CustomRow but that doesn't work when you start sorting since the every fourth row could get sorted into another sequence.
So in essence I'm asking for Auto numbering column to get at using the CustomRow feature and back into the sticky header use.

Oh. Did I mention that this component is awesome!!
