If you use the table editor properly, it will keep the formulas up to
date for you. For instance, if you place your cursor on item2 and
press return, a new line should be created and the formulas cell
references corrected to match.

Beware commands line C-k that may delete a row as text instead of
using the Org-Mode specific table editing commands. If you want to
delete a line like C-k, use M-S-Up instead.
