[OOP] How do I return and get another table

[LabiVila]

Hello so my question is, how can I create another table and get returned that and not self? I'm a beginner in OOP and so far I've achieved somehow what I wanted with this:

  
local players = {} 
local count = 0 
  
function players:addPlayers (name, age) 
    count = count + 1 
    local list = {} 
    
    setmetatable (list, self) 
    
    self [count] = {name = name, age = age} 
    
    return self 
end 
  
function players:getAll () 
    return self 
end 
  
addCommandHandler ("add", 
    function (_, _, a, b) 
        players:addPlayers (a, b) 
    end 
) 
  
addCommandHandler ("go", 
    function () 
        ai = players:getAll () 
        
        for i,v in pairs (ai) do 
            if (tonumber (i)) then 
                outputChatBox (v.name.." "..v.age) 
            end 
        end 
    end 
) 
  

but If I loop through the self table, I get all function names (getPlayers, addPlayers and I don't know why) and I want a clear table for my players, not the 'self' one.

thank you further
