How could i insert a table that is the player's name into a dictionary?

So basically, in a nutshell, I'm attempting to sort an inventory system by putting multiple tables of values into other tables, however I am stumped at how i can achieve this.

local events = game.ReplicatedStorage.Inventory
local playerInventories = {

}
events.PickingUp.OnServerEvent:Connect(function(p,mouse)
    if mouse.target:FindFirstChild("PickUpValue") ~= nil and (p.Character.UpperTorso.position-mouse.hit.p).magnitude <= 10 then
        if playerInventories.p == nil then
            local p = {}
            table.insert(playerInventories,p{})
        end
    end
end)

EDIT: Thanks for any help
