Please verify the correct functionality.

See the example below. The results were obtained by selecting
the columns from left to right, and changing its values

This shuffling can be simualted by

dBTable1.moveColumn(2,0);
dBTable1.moveColumn(1,2);

QuickTable 2.0.5.20 (Free Version)
oldValue = col=1 origCol=2
oldValue = R0C2 col=2 origCol=1
oldValue = R0C1 col=3 origCol=0

with the moveColumn() lines removed

QuickTable 2.0.5.20 (Free Version).
oldValue = R0C1 col=1 origCol=0
oldValue = R0C2 col=2 origCol=1
oldValue = col=3 origCol=2
