Datatable: Uncaught TypeError: Невозможно прочитать свойство 'style' из неопределенного

Question

Я использую вложенные данные, чтобы показать список жалоб для отдела.По умолчанию все жалобы категории извлекаются из базы данных.Это работает нормально.

Когда я меняю раскрывающийся список и выбираю другую категорию, таблица данных не загружается новыми значениями.На консоли браузера появляется следующая ошибка:

JS-код для получения данных из базы данных:

//get complaint data from database
    function getComplaintData(){
        var cat = $("#mainCategory").val();            
        $.ajax({
                url: 'getComplaintData',
                type: 'POST',                   
                data:{ "userLogged":"admin","category":cat},
                success: function (data) {                         
                    assignToEventColumns(data); //bind to datatable             
                    bindDetails(); //bind to nested table of datatable
                }                   
        });            

    }       
   $(function(){            
        getComplaintData();           
           // Add event listener for opening and closing details              
    });



var table;
//assign complaint data to datatable
function assignToEventColumns(response){         
var complaintId,complaintDt;

 table = $('#dtMyComplaints').DataTable({ 
  destroy: true,
  "processing": true,

                if(data.status=="C"){
                    return "";

    {"data":"item",visible:false,targets:[8]},
    {"data":"category",visible:false}

}

Ответ из базы данных имеет формат:

Answer 1

Данные должны быть уничтожены, если они существуют.

if (mytable !== null ) {      
        $('#dtMyComplaints').DataTable().destroy();
        mytable = null;
        // empty in case the columns change
        $('#dtMyComplaints').empty();
    }  

затем код для создания таблицы данных.

  table = $('#dtMyComplaints').DataTable({ ......});
