If you only want to put the second table at the right of the first one I think
that the functions kill-rectangle and yank-rectangle are enough. Select the
second table (without the first | char) and run the command kill-rectangle (C-x r
k), then put the cursor at the end of the first line of the first table and run
the command yank-rectangle (C-x r y).
