Change column name in a grid with CellEditor

Hello guys,

Please, I need your help to get the following effect on a grid using the CellEditor:

Laranja		Pera		Maca
ValueA-1	ValueA-2	ValueB-1	ValueB -2	ValueC-1	ValueC-2
10	xxx	5	zyz	20	opx
2	bbb	1	abc	7	zzz
3	ccc	3	www	8	ppp

These are the data and fields returned in my JSON:

Field-A	ValueA-1	ValueA-2	Field-B	ValueB-1	ValueB-2	Field-C	ValueC-1	ValueC-2
Laranja	10	xxx	Pera	5	zyz	Maca	20	opx
Laranja	2	bbb	Pera	1	abc	Maca	7	zzz
Laranja	3	Ccc	Pera	3	www	Maca	8	ppp

Any help will be appreciated, therefore, still have not found someone who could help me solve this issue.

hugs
