The number of columns is limited to 256 columns. This cannot be
increased.

My excel sheets have by default up to column IV (aprox. 266
columns). I need
to insert more than this and also have problems with the option
of "grouping"
columns. When I have most of 266 columns in use and several
"groupings", when
I try to minimise them all (one by one), after a few, appears a
warning pop
up messge with a message "objects cannot be moved outside the
sheet" and the
action cannot be done (cannot mimise that group of columns and
not anymore
until I expand/ungroup others).
