How would I save a table to a datastore?

I am tryng to save mutltiple values that I create when the player's enter. I can save a single value just fine but I realized I need a table to store other values to. I can run the script with no error but it prints the default values instead of the one's from my last playing session. Ideas?

--Get The Service's
local replicatedStorage = game:GetService("ReplicatedStorage")
local timePlayedValue = replicatedStorage:WaitForChild("TimePlayedValue")
local totalTimeValue = replicatedStorage:WaitForChild("TotalTimeValue")
local httpsService = game:GetService("HttpService")
local dsService = game:GetService("DataStoreService")
local mainStore = dsService:GetDataStore("MainDataStore")

--create player data
