Is there any effect if i change the column value in Minitab Taguchi DOE design??

#1
Hello all,

I am trying to design Design of Experiment using Minitab statistical software using Taguchi approach. I have 3 level and four factors.
When I go Minitab-->stat-->DOE-->Taguchi-->3level design with 4 factors i.e L27 (3**4)
there will appear factors, name, level values, column, and level.
I can edit name, level values and column value as desired. if I select default column value it gives same set of experiments three times.

if i change the column value is there any effect in my DOE?? please explain....

Thanking you
