Json在Golang中解码/解组

I have the following json:

{"results":
[{"columns":["room_id","player_name","player_ip"],
  "types":["integer","text","text"],
  "values":[[1,"alice","127.0.0.1"]
            [1,"bob","127.0.0.1"]],
  "time":0.00018839100000000002}]}

where values can have any number of elements [] inside them. When i try to unmarshal the json into a struct, the "values" tag does not get parsed properly

struct:

type queryResults struct {
        Results []struct {
            Columns []string `json:"columns"`
            Types []string `json:"types"`
            Values []struct {
                Room_id int
                Player_name string
                Player_ip string
            } `json:"values"`
            Time float64 `json:"time"`
        } `json:"results"`
    }

Code:

//jsonString is the string input to Unmarshal
resultjson := queryResults{}
json.Unmarshal([]byte(jsonString), &resultjson)
fmt.Printf("%+v",resultjson)

Current Output:

{Results:
 [{Columns:[room_id player_name player_ip] 
   Types:[integer text text] 
   Values:[{room_id:0 player_name: player_ip:} 
           {room_id:0 player_name: player_ip:}] 
   Time:0.00018839100000000002}]}

Expected Output:

{Results:
     [{Columns:[room_id player_name player_ip] 
       Types:[integer text text] 
       Values:[{room_id:1 player_name:alice player_ip:127.0.0.1} 
               {room_id:1 player_name:bob player_ip:127.0.0.1}] 
       Time:0.00018839100000000002}]}
