Re: [O] table formula help...

[Thierry Banel]

Ok, done.
A clean design has been implemented for handling empty cells.

Basically, empty input cells are ignored, and therefore they do not
participate in the aggregation. (However, for aggregation using two
columns (=corr(p,q)= for example), if a pair of cells contains both an
empty and a non-empty cell, then the empty one is replaced by zero.)

On output, empty cells are generated when the aggregation function does
not have enough input. For instance, =mean= needs at least one value,
otherwise a division by zero happens.

Thanks to Michael Brand for his insight and suggestions.
