Lua的Table表使用例子（便于使用查询）

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)

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

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)

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0
4     print("Countries Maxn  >> "..table.maxn(countries))
5     print("Cars Maxn  >> "..table.maxn(Cars))
6     dump(countries)

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))

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))

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

 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)
