Adding to tables with script?

So I am creating a script that should save the children of an object's names and cframes in the same order, in two tables, kind of like a table with a key. I would be able to save object sand their cframes in that way. What i need to do now is add things to a different table and in the same order as the first table. I think that the script below may work but i still cannot find how i would make and add things to a table with script.

Script

	while true do
		wait(60)
		local pur=script.Parent.Parent.Parent.Purchased
		local pnumb=#pur:GetChildren()
		local table={}
		local purs=pur:GetChildren()
		PlayerData:SetAsync(("objects".. plyr.UserId),{purs})
		for i=1, pnumb do
			local puri = table.remove(purs,i)
           			 --Here is where i would like it to add puri to a new table called table
        		end
		end
		PlayerData:SetAsync(("cframes".. plyr.UserId),{table})
	end
