How to check if two tables(objects) have the same value in Lua

Question

I wanna check if two tables have the same value in Lua, but didn\'t find the way.

I use the operator ==, it seems just to check the same objects, but no

Answer 1

There is no built-in function for comparing tables by contents.

You'll have to write your own. You'll need to decide whether you want to compare tables by contents shallowly or deeply. See https://web.archive.org/web/20131225070434/http://snippets.luacode.org/snippets/Deep_Comparison_of_Two_Values_3 for some ideas.
