Its true, i havent thought of the implications of what it means to switch rows. Should
references pointing to cell A1 remain pointing to A1, when the content of A1 is
"traded" for the content of B1? What should the references follow?
But apart from that, the way to exchange two rows is I believe indeed achieved
most easily by a combination of the insert_row(), move_row(), delete_row()
methods.
If you want to swap the contents of two rows or columns but you do not want to
change their references, it might be a set of
1. insert_row as a temporal space,
2. COPY_row 1 to the temporal space,
3. COPY_row from 2 to 1,
4. COPY_row from the temporal row to 2,
5. and delete_row the temporal space.
It might look like:
int a = 1;
int b = 2;
int t;
t = a;
a = b;
b = t;
