Can Someone Help Saving Tables to DataStore?

I have been trying to write a datastore script I was able to create a table but as far as saving it I am not sure how to. I have tried using functions but i want to be able to save the table and update it when the player leaves. Here is the Code:

local DSService = game:GetService("DataStoreService"):GetDataStore("Test")

game.Players.PlayerAdded:Connect(function(plr)
	local key = "player-"..plr.UserId
	local savedStats = DSService:GetAsync(key)
	if savedStats then
		-- not sure what to put here
	else
		local Data = {
			Currency = {Coins = 50, Points = 30},
			Inventory = {},
			Values = {Gamepass = false}
		}
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local key = "player-"..plr.UserId
	DSService:SetASync(key,) -- not sure how to save the table when a player leaves
end)

I would like to be able to save the table when the player leaves without having intvalues. Is this possible if so any help would be greatly appreciated.
