Place an object on the headers:

CREATE TABLE DATA (field1 c(5), field2 c(5))
FOR i = 1 TO 20
	APPEND BLANK
	REPLACE field1 WITH [Hello]
	REPLACE field2 WITH [World]
ENDFOR
GO TOP

PUBLIC oForm1
oForm1 = CREAT([oForm])
oForm1.AUTOCENTER = .T.
oForm1.SHOW

DEFINE CLASS oForm AS FORM
	ADD OBJECT oGrid1 AS oGrid
	ADD OBJECT oNoSizing1 AS oNoColumnResize WITH ;
		LEFT = 25
ENDDEFINE

DEFINE CLASS oGrid AS GRID
	TOP = 20
	LEFT = 25
ENDDEFINE

DEFINE CLASS oNoColumnResize AS SHAPE
	BACKSTYLE = 0
	WIDTH = 303
	HEIGHT = 20
	TOP = 20
ENDDEFINE
