Alphabetical order?
That is not what the manual says:
Sort
Sorts the order of elements on an axis in ascending order. Note that in multidimensional arrays this sorts based on the first element on the axis. For example sorting the X axis in a 2D array will sort the order of the columns based on the elements at Y co-ordinate 0, while preserving the contents of each column.
It should order all the rows taking in count only the first column.
But you are right, I tried again and it orders every column by itself.
Wow! So it's even more useless than I though.
Thanks for your answer.
