i have one excel sheet and i made it shared for multiple users. i want when
any 2 or many users open it at the same time and start to type in it, the
first one who will type should block others to type in the same raw.
i mean for example, if user A opens the sheet and start to type in raw 20, i
want that this raw will appear in diferent color in the same time to any
other users and so on.
thx for your great support
