I suggest that I will improve the TBLFM example about "nan" in the
manual like this:
`if("$1" == "nan" || "$2" == "nan", string(""), $1 + $2); E f-1'
Sum of the first two columns. When at least one of the input
fields is empty the Org table result field is set to empty. `E'
is required to leave empty fields without conversion to 0. `f-1'
is an optional Calc format string similar to `%.1f' but leaves
empty results empty.
Would this have answered all your questions?
Michael
