What is a tableTable is the most powerful data type in Lua, and we can think of it as an array, but it's a bit different from the group, and it's recommended that you look at Lua's grammar tutorials, because I'm not familiar with table to explain to you.(Narrator: What other tutorials do you write ...)

The previous LUA-C interaction function Registration describes how to register C functions with Lua for use in Lua.When the C-provided interface for fetching data is called in Lua, how does C convert multiple struct types to LUA's nested table types?
Here is an example to illustrate the C data type

In the next step, we will use it.First, we need to determine which binding files we generated through the Python script. Let's list a form. //Path:f:\cocos2dx-lua
1. Introduction
Lua has only one basic data structure, that is, table. All other data structures, such as arrays,
Can be implemented by table.
2. Table subscript
Example e05.lua
-- Arrays myData = {} myData[0] = “foo” myData[1] = 42 -- Hash tables myData[“bar”] = “baz” -- Iterate through the -- structure for key, value in myData do print(key .. “=“ .. value) end
Output result
0 = foo
1 = 42

The essence of a Lua table is actually something similar to hashmap. Its elements are many key-value pairs. If you try to access elements that do not exist in a tableA set of search mechanisms that trigger Lua can also be used to achieve "Object-Oriented.Example:
Temptable = {}
Print (temptable. membera) -- try to print members that do
