Well, there is an alternative solution to Ken's: in fact two. Ken computes
the number for each item as a function of information in the source, which
is a perfectly reasonable approach in this case but doesn't work for all
such problems. 

Plan B is to process the source records using recursion: write a
function/template that processes one input record, then calls itself to
process the remainder. On the recursive call, you can pass parameters that
represent the current state, for example a number which increments on each
call.

Plan C is a two-phase transformation: first generate the output table, then
in a second pass, number its cells.
