The precise thing that I want makes it not viable to create a new column, because _f_ will not remain a function, but a _series_ of functions - and creating one new column for each _f_ is not adequate. Namely: there is a table with values A[i] and Z[i]. There is another table with values F[j] [and here I use different indexes on purpose]. I want to make column G[j] as... G[j] = sum over i ( function of (F[j], A[i] and Z[i])) So, the extra-column solution won't work. I would like something like: G[j] = SUM( etc etc F[j] etc etc A1:A1000 etc etc Z1:Z1000) but somehow this construct does not work.
