OO bleg

Anyone know if there’s an invert macro for OpenOffice Calc and where it can be found? I know there’s a Transpose function, but that only turns a vertical column into a horizontal row. I want to take the cells in a single column and reverse the order so that:

A

B

C

becomes

C

B

A

I have the macro running in Excel, of course, but I don’t want to reboot into Windows just to flip a column.
