How do i save a table with datastore?

Im trying to save a table with datastore but it never works. Please help!

local dss = game:GetService("DataStoreService")
local ds = dss:GetDataStore("HatInv")


game.Players.PlayerAdded:Connect(function(p)
	local Data = ds:GetAsync("User-"..p.UserId)
	local Data2 = table.unpack(Data)
	if Data2 ~= nil then
		for i, v in pairs(Data2) do
			local findObject = game.ReplicatedStorage.Hats:FindFirstChild(v):Clone()
			findObject.Parent = p:WaitForChild("PlayerGui").ScreenGui.Inventory.ScrollingFrame
		end
	else
		warn(Data)
	end
end)
game.Players.PlayerRemoving:Connect(function(p)
	local ToBeSaved = {}
	for i, v in pairs(p:WaitForChild("PlayerGui").ScreenGui.Inventory.ScrollingFrame:GetChildren())
	do
		if v.ClassName == "Frame" then
			table.insert(ToBeSaved, v.Name)
		else
				
		end
		
	end
	ds:SetAsync("User-"..p.UserId, ToBeSaved)
end)

Thanks in advance
