how create table classes?

[LANAK06]

table classes of DarkRP
local base = {
color = Color(0,0,0,255),
model = "",
description = "No description provided",
weapons = {},
command = "cmd",
max = 0,
salary = 0,
admin = 0,
vote = false,
hasLicense = false,
NeedToChangeFrom = nil,
customCheck = nil
}

RPExtraTeams = {}
function AddExtraTeam(name, t)
local base = table.Copy(base)
table.Merge(base, t)
t = base

t.name = name

local n = table.insert(RPExtraTeams, t)
if n == 1 then
PrintTable(t)
end
team.SetUp(n, name, t.color)

timer.Simple(0, function() GAMEMODE:AddTeamCommands(t, t.max) end)

if type(t.model) == "table" then
for k,v in pairs(t.model) do util.PrecacheModel(v) end
else
util.PrecacheModel(t.model)
end
return n
end
my table create
local tеst = {
color = Color(0,0,0,255),
model = "",
}
tests = {}
function test(name,t)
local test = table.Copy(test)
table.Merge(test,t)
t = test
t.name = name
local t = table.insert(tests, t)
if type(t.model) == "table" then
for k,v in pairs(t.model) do util.PrecacheModel(v) end
else
util.PrecacheModel(t.model)
end
return t
end
Is what i doing wrong?
