rakanugro

so far I can display data properly from datatables,when I use the columns[] on ajax script to make edit/delete
the data can't display properly here my code

view:

<table id="example" class="display" cellspacing="0" width="100%">
                    <thead>
                        <tr>
                            <th>ID Category Asset</th>
                            <th>Category Name</th>
                            
                        </tr>
                    </thead>
                 
                    <tfoot>
                        <tr>
                             <th>ID Category Asset</th>
                            <th>Category Name</th>
                        </tr>
                    </tfoot>
                 
                 
                    <tbody>
                        
                    </tbody>
                    </table>

controller

public function ac_page(){

        $this->load->model('edit_model');
        $ac = $this->edit_model->load_ac();
        
        //variables
        $draw = intval($this->input->POST('draw'));
        $start = intval($this->input->POST('start'));
        $length = intval($this->input->POST('length'));

        $data =  array();

        foreach ($ac as $row ) {
            
            $data[] = array(

                $row->Category_ID,
                $row->Category_name

                );

        }

        $acfull = $this->edit_model->load_acfull();

        $output = array(

            "draw" => $draw,
            "recordstotal" => $acfull,
            "recordsfiltered" => $acfull,
            "data" => $data

            );

        echo json_encode($output);
        exit();

    }

ajax

$(document).ready(function() {
             $('#example').DataTable({
                
                "processing": true,
                "ajax" :{
                  url : "<?php echo base_url()?>Edit_asset/ac_page",
                  type : 'POST'
                },
                //"columns": [
                  //{ "data": "Category_ID" },
                  //{ "data": "Category_name" }
                //]

            });

           });

the question is how to make edit/delete and display data properly
