I am using groupBy()
I would like to know:
- if it is possible to put into a group title value from the fifth column “COIL DESCR” (it is a sting and it always has the same values withing a group) and how?
- how can I format fourth column “BATCH”, so I it will be shown in a group title like “0016” instead of “16”. I’ve tried to use setNumberFormat(), but it didn’t solve the problem.
