   "cache": 500
   },
   "initFetch":false,
   "columns": [
   {
     "name": "id",
     "type": "text",
     "static": true,
     "label": "用户ID"
   },
   {
     "name": "updateTime",
     "format": "YYYY-MM-DD HH:mm:ss",
     "inputFormat": "YYYY-MM-DD HH:mm:ss",
     "type": "input-datetime",
     "label": "更新时间"

   ],
   "filter": {
