  "table": {
    "columns": {
      "userShowName": {
        "attrs": {
          "positionType": "expand"
        }
      },
      "openId": {
        "attrs": {
          "positionType": "main"
        }
      },
      "createDate": {
        "attrs": {
          "positionType": "main"
        }
      }
