How can you tell if a value is a table?

Say your making a script and by the end of it you tell it to return a value. You don't know what kind of value it is but you hope it's a table. How would you go about confirming that the value is a table?

By using the type function!

tab = {}
print(type(tab))

if type(tab) == "table" then
	print("This will print!")
else
	print("but this won't! D:")
end
