Getting the name of a dictionary

Hi!

I have this dictionary here inside a module script:

local module = {}

module.Packs = {
	
	["Naruto Pack"] = {
		
		["Card1"] = "Naruto S1",
		["Card2"] = "Sasuke S1",
		["Card3"] = "Sakura S1",
		["Card4"] = "Kakashi S1",
		["Card5"] = "Gaara S1"
		
	},
	
	["One Piece Pack"] = {
		
		["Card1"] = "Luffy S1",
		["Card2"] = "Zoro S1",
		["Card3"] = "Nami S1",
		["Card4"] = "Robin S1",
		["Card5"] = "Sanji S1"
		
	},
	
	["Dragon Ball Pack"] = {
		
		["Card1"] = "Goku S1",
		["Card2"] = "Gohan S1",
		["Card3"] = "Krillin S1",
		["Card4"] = "Piccolo S1",
		["Card5"] = "Vegeta S1"
		
	},
	
}

return module

I was wondering how I could retrieve the name of the tables inside. So “Naruto Pack”, “One Piece Pack” etc. Right now I can only get it to print the index.

for PackName in pairs(module.Packs) do
	print(PackName)
end
