Lua How to find the position information I want in an array?

I need to find the information based on the position of each array.
Lua: 
local arrayVoc = {
   [1] = {1, 2, 3, 4, 5},
   [2] = {6, 7, 8, 9, 10},
   [3] = {11, 12, 13, 14, 15},
   [4] = {16, 17, 18, 19, 20},
   [5] = {21, 22, 23, 24, 25},
   [6] = {26, 27, 28, 29, 30}
}

Currently the search system searches based on the vocation of the player. But that's not enough that I need.
Lua: 
if isInArray(arrayVoc[1], player:getVocation():getId()) then
  ...
end

For example: I need to get the information that is in [2] and position 3. Would the result be 8 or 9? If it starts with 0 it would be 9, but if it starts with 1 then it is 8.

How do I build the formula to find the value of the position I want?

Thank's

Array [1][2] will give you the first array, third positiin. Arrays are zerobased, so first position is 0.

no they are not, arrays in lua begin at 1
if they were your statement should have been array[0][2], array[1] would be 2nd array if lua started indexing at 0 instead of 1

i don't really understand what exactly you want but i threw this together to make it check for ids in each table instead of just 1
Lua: 
local arrayVoc = {
   [1] = {1, 2, 3, 4, 5},
   [2] = {6, 7, 8, 9, 10},
   [3] = {11, 12, 13, 14, 15},
   [4] = {16, 17, 18, 19, 20},
   [5] = {21, 22, 23, 24, 25},
   [6] = {26, 27, 28, 29, 30}
}

isInArray = function(t, v, deep)
    for k, val in pairs(t) do
        if type(val) == 'table' and deep then
            return isInArray(t, val, true)
        else
            if val == v then
                return true
            end
        end
    end
    return false
end

print(isInArray(arrayVoc, player:getVocation():getId(), true))

Mhm, to be honest, i though they started by Zero. But you are right. And about my statement, it wasn't wrong because in case he declare an array as he is doing, he can access directly by the key, which is "1" for the first array. Thats why i did it that way. :p

Thank you. But can you help me build this code below? He's making a mistake, and I think you can understand what I've tried to do.

EDIT.: I find a error, I'll show again, cheking...
EDIT 2: Here is the revised code , but it has an error.

Lua: 
for _, v in pairs(arrayVoc) do
    if type(v) == 'table' then
        if isInArray(v, player:getVocation():getId()) then
            player:setVocation(arrayVoc[v][1])
        end
    end
end

If you have an error you have to supply the error not just say it has an error, most especially since its not a complete script.

Sorry sir. Error in line 41 when addOutfit.
Lua:
