Ah wow!  Thanks Christian!  I, at least, am very happy and content about
this subject-thread!

MLeft and MRight work great in TableMode of EmacsOrgMode!

Agree too: Rectangle editing is slower than Christian's method--EmacsOrgMode
has blown me away all over again!

Christian's method is a manual one though, Juan's and Dan's are program/app
based--there is more than one way to skin a cat.

All of the methods @do@ help one sort columns (in the way Gary described) in
OrgMode.

But still, playing devil's advocate here: There are those disappearing
hlines in Juan's method--maybe there is some code to write here.
