This goes in top work sheet as "Utilities"
This module is to be developped wrt to cols
Here we have preselected cols [1,3]. 
At this point, you can select any rows  in
cols [1,3] or as otherwise preselected. 
Next: add/delete/insert/shuffle rows at will.
Mathcad 11 could NOT do that. data row ListCollect ct 1 : i row a ct el data i 1 el : b ct el data i 3 el : ct ct 1 + : 31 line for a b augment 31 line :

Mathcad 11.2a does it same way except for: 1. Little different coding 2. col & row must be respectively stacked col:=stack(1,3,5) row:=stack(2,3,4) In that form you can => add/remove/insert/shuffle
