I changed those things

self.db.profile.headers["PRHeaderColumn"] = setmetatable({}, {__index=self.headerDefaults})
	local column = self:CreateRaidFrame("PRHeaderColumn", nil, "1,2,3,4,5,6,7,8", nil)
	column:Hide()
	column:SetAttribute("groupBy", "GROUP")
	column:SetAttribute("groupingOrder", "GROUP1,GROUP2,GROUP3,GROUP4,GROUP5,GROUP6,GROUP7,GROUP8,GROUP9")
	column:SetAttribute("maxColumns", 1)
	column:SetAttribute("unitsPerColumn", 40)
	column:SetAttribute("columnSpacing", 10)
	column:SetAttribute("columnAnchorPoint", "LEFT")
	self:RestorePosition("PRHeaderColumn")
	column:Show()

But still not working :/
