use diff function, see its help page for right formulation

You can use {} notation using : (colon) for the row numbers and using numeric values for column numbers. You can even
diff(YourTable{:, :}, [], 2)
to find the difference between adjacent columns.
What I do not know at the moment is whether there is a nice way to rearrange columns. You can probably use
YourTable(:, [3 1 4 2])
for example to rearrange columns including header.
