一、table.insert()

1.1

1     local countries = {"China", "England", "Brazil"}2     --尾插法（Pos不填，默认插入尾部）3     table.insert(countries, "France")4     --头插法（首部插入）5     table.insert(countries, 1, "Australia") 6     7     dump(countries)

二、table.remove()

2.1

1     local countries = {"China", "England", "Brazil", "England"}2     table.removeItem(countries, "England", true)3     dump(countries)

2.2

1     local countries = {"China", "England", "Brazil", "Australia"}2     --移除位置2上的元素（“England”）3     table.remove(countries, 2)4     --默认尾部删除元素5     table.remove(countries)6     dump(countries)

三、table.maxn()

3.1

1     local countries = {"China", "England", "Brazil", [7] = "Australia"}2     local Cars = {[-3] = "Benz", [-2] = "Toyota", [-1] ="LandRover"}3     --获取table的最大下标。如下标小于0，则返回04     print("Countries Maxn  >> "..table.maxn(countries))5     print("Cars Maxn  >> "..table.maxn(Cars))6     dump(countries)

四、table.concat()

4.1

1     local countries = {"China", "England", "Brazil","Australia"}2     --用“+”拼接table中的元素（table[1].."+"..table[2]..………….."+"..table[n]）3     print("拼接:  "..table.concat(countries, "+"))4     print("从Pos[3]开始拼接:  "..table.concat(countries, "+", 3))

4.2

1     local countries = {"China", "England", "Brazil","Australia"}2     --table.concat(table, "X", began, end)3     --从began的位置，用"X"连接到end位置结束4     print("拼接:  "..table.concat(countries, "+", 2, 3))

五、table.sort()

5.1 

1     local countries = {"China", "England", "Brazil","Australia"}2     table.sort(countries)3     dump(countries)

5.2

 1     local countries = {"China", "England", "Brazil","Australia"} 2     --自定义排序方式 3     myComparator = function(a, b)  4         if a > b then 5             return true 6         else  7             return false 8         end 9     end 10     table.sort(countries, myComparator)11     dump(countries)
