Set Individual Column color: obj.getColumnTemplate(...)

I have read through a lot of Q&A in this Forum.
Every answer points to calling function below:

obj.getColumnTemplate(2).setStyle("color", myColor);

Wouldn't this change color of the WHOLE column? That's what happens to me. I have tried a lot of ways (loops,...), none worked.

I done see where it indicate which "Row" to change, only column "2", in this case. Any one agree? Any function that I can use to specify both
the Row and the Column?

in v2:
obj.getCellTemplate(col,row).setStyle("property",<method/value>);
will do the job.
