H?ow do I do a i,v loop inside a i,v loop in a table

So I found this loophole that I couldn't think of any other solution to get around

local tab = {Tab1 = {Tab1x = {}}, Tab2 = {Tab2x = {}}, Tab3 = {Tab3x = {}}}

for i,v in pairs(tab) do
	for k,e in pairs(v) do
		print(e)
		
		-- and so on 
	end
end

How would I do a iv loop succesfully without looping multiple times because of the iv loop on top
