Google-sheets – Grouping columns in Google spreadsheets (and summarize them)

google sheets

Lets say I have a table like this:

A | B | C

1 | 4 | 3

Is it possible to group these columns together so that I can expand and collapse them with a specific formula. For example with SUM I would have one single column:

ABC

 8

And after that expand them again if I need the detailed data.

This is very easy with hiding/unhiding columns but not possible with a formula.
