==============变量类型
nil
number(实数) 1 2 3.14 7.65e8
string "hello world" "\n"
boolean(true false) true false
function
*userdata and threads
table
(1)默认key初始化
t = {a, "hello", b, "world"}
(2)自定义key初始化
t = {n1 = a, n2 = "hello", n3 = b, n4 = "world"}
t.n1 or t[1] or t["n1"]
(3)元素添加赋值
Data = {}
Data.name = "Thardwick"
Data.class = "Barbarian"
Data.str = math.random(3, 18)
Data.dex = math.random(3, 18)
Data[1]
Data.name
Data.["name"]
多维tab
widget = {}
widget.name = {"can opener", "Scissors"}
widget.cost = {"$12.75", "$8.99"}
