these two should be equivalent, if aria-colindex is omitted then cell index
equals previous cell index + 1. If aria-colindex is lesser or equals to
previous colindex then it's ignored.

This is a new scenario we didn't consider yet so far. I thought that only
continue set of rows or columns may be missed. So is it valid scenario when
each row can contain different subsets of missed rows?
