The thought of lifting and shifting dozens of cells by hand is filling me with dread !

Come on, these are just 5 dozen. About a quarter of an hour if you manage to lift and shift 4 cells per minute.

To begin with programmatically, I'd describe first which cell from the origin table goes to which cell of the destination table, then write a program to do it, making some loops which iterate over the origin rows and cells. If something fails, I'd come back here and ask specifics, posting my code.
