Lua的Table表使用例子（便于使用查询）

local countries = {"China", "England", "Brazil"}
--尾插法（Pos不填，默认插入尾部）
table.insert(countries, "France")
--头插法（首部插入）
table.insert(countries, 1, "Australia")

dump(countries)

local countries = {"China", "England", "Brazil", "England"}
table.removeItem(countries, "England", true)
dump(countries)

local countries = {"China", "England", "Brazil", "Australia"}
--移除位置2上的元素（“England”）
table.remove(countries, 2)
--默认尾部删除元素
table.remove(countries)
dump(countries)

local countries = {"China", "England", "Brazil", [7] = "Australia"}
local Cars = {[-3] = "Benz", [-2] = "Toyota", [-1] ="LandRover"}
--获取table的最大下标。如下标小于0，则返回0
print("Countries Maxn  >> "..table.maxn(countries))
print("Cars Maxn  >> "..table.maxn(Cars))
dump(countries)

local countries = {"China", "England", "Brazil","Australia"}
--用“+”拼接table中的元素（table[1].."+"..table[2]..………….."+"..table
）
print("拼接:  "..table.concat(countries, "+"))
print("从Pos[3]开始拼接:  "..table.concat(countries, "+", 3))

local countries = {"China", "England", "Brazil","Australia"}
--table.concat(table, "X", began, end)
--从began的位置，用"X"连接到end位置结束
print("拼接:  "..table.concat(countries, "+", 2, 3))

local countries = {"China", "England", "Brazil","Australia"}
table.sort(countries)
dump(countries)

local countries = {"China", "England", "Brazil","Australia"}
--自定义排序方式
myComparator = function(a, b)
if a > b then
return true
else
return false
end
end
table.sort(countries, myComparator)
dump(countries)
