Answer 1

您身边的名字附带的数据并不相同，因为您输入了错误。

  

你必须这样做。

columns:["Id", "name", "gender", "pincode", "City"]

  

或

     columns: [
     { dataField:'Id',    caption: 'ID'},
     { dataField:'name',   caption: 'Name'},
     { dataField:'gender',caption: 'Gender'},
     { dataField:'pincode',caption: 'Pincode'},
     { dataField:'City'}],
