类似于数据格式: https://blog.csdn.net/qq_44072222/article/details/120884158
目标json格式
{"位置": 1, "名称": "nba球员", "国家": "美国", "级别": "top10", "level2": [{"模块": "jordan", "球衣号码": 23, "球队名称": "公牛", "level3": [{"技术": "中投", "分数": 10}, {"技术": "三分", "分数": 5}, {"技术": "篮下", "分数": 8}, {"技术": "扣篮", "分数": 9}, {"技术": "忠诚度", "分数": 9}, {"技术": "人品", "分数": 6}]}, {"模块": "james", "球衣号码": "8、24", "球队名称": "骑士", "level3": [{"技术": "三分", "分数": 7}, {"技术": "篮下", "分数": 10}, {"技术": "扣篮", "分数": 9}, {"技术": "忠诚度", "分数": 5}]}, {"模块": "kobe", "球衣号码": "23、6", "球队名称": "湖人", "level3": [{"技术": "中投", "分数": 10}, {"技术": "忠诚度", "分数": 10}]}]}

整体思路
数据格式相等于是一个三层的的树，一次遍历第一层，第二层， 第三层然后构建一颗树即可
第一层: 列范围 1-4
第二层: 列范围 5-7
第三层: 列范围 8-9
关键参数
表示三层
每次定位到第一层然后范围依次缩小取位置
col_level_index = [1, 5, 8, 10] # level1, level2, level3, level4
