    */
   if (!class_exists('WP_List_Table')) {
       require_once( ABSPATH . 'wp-admin/includes/class-wp-list-table.php' );
   }
   
   class wplist_table extends WP_List_Table
   {
   
       //put your code here
       var $data = array();
       var $default_columns = array();
   
       public function wplist_table($datad, $columns)
       {
           parent::__construct();
   
           $this->data = $datad;
           $this->default_columns = $columns;
       }
   
       function get_columns()
       {
   
           return $this->default_columns;
       }
   
       function prepare_items()
       {
           $columns = $this->get_columns();
           $hidden = array();
           $sortable = $this->get_sortable_columns();
           $this->_column_headers = array($columns, $hidden, $sortable);
           usort($this->data, array(&$this, 'usort_recorder'));
           $per_page = 10;
           $current_page = $this->get_pagenum();
           $total_items = count($this->data);
   
           // only ncessary because we have sample data
           $this->found_data = array_slice($this->data, (($current_page - 1) * $per_page), $per_page);
   
           $this->set_pagination_args(array(
               'total_items' => $total_items, //WE have to calculate the total number of items
               'per_page' => $per_page                     //WE have to determine how many items to show on a page
           ));
           $this->items = $this->found_data;
       }
   
       function column_default($item, $column_name)
       {
           foreach ($this->default_columns as $keys => $values) {
               if ($values == $column_name) {
                   if(isset($item[$column_name])){
                       return $item[$column_name];
                   }
               }
           }
       }
   
       function get_sortable_columns()
       {
   
           $i=0;
           $sortables = array();
           foreach ($this->default_columns as $keys => $values) {
   
               if($i == 0){
                   $i++;
                   //continue;
               }
                   $sortables[$keys] = array($values,false);
           }
           return $sortables;
       }
   
       function usort_recorder($a, $b)
       {
           $orderby = (!empty($_GET['orderby'])) ? $_GET['orderby'] : 'id';
   
           $order = (!empty($_GET['order'])) ? $_GET['order'] : 'asc';
   
           $resutl = strcmp($a[$orderby], $b[$orderby]);
           return ( $order === 'asc') ? $resutl : -$resutl;
       }
   
       function column_Name($item)
       {
           $action = array(
               'edit' => sprintf('<a href="?page=%s&action=%s&fields=%s">Edit</a>', $_REQUEST['page'], 'edit', $item['id']),
               'delete' => sprintf('<a href="?page=%s&action=%s&fields=%s">Delete</a>', $_REQUEST['page'], 'delete', $item['id'])
           );
           return sprintf('%1$s %2$s', $item['name'], $this->row_actions($action));
       }
   
       function get_bulk_action()
       {
           $actions = array(
               'delete' => 'Delete '
           );
           return $actions;
       }
   
       function column_db($item)
       {
           return sprintf("<input type='checkbox' name='id[]' value='%s'", $item['id']);
       }
   
   }
   
   ?>
   

   just you copy that code in file and pass arguments like column name and data like this.

     $data = array(
       array("id" => 1, "name" => "Renish Khunt", "add" => "asd"),
       array("id" => 2, "name" => "Renish Khunt", "add" => "asd"),
       array("id" => 3, "name" => "Renish Khunt", "add" => "asd")
   );
   $columns = array(
       "name" => "name",
       "add" => "add"
   );
   

   then after create the class object and pass the two arguments the data and column name like this.

   $mylist_table = new wplist_table($data, $columns);
   echo '<div class="wrap"><h2>Custome Fields<a class="add-new-h2" href="?page=' . $_REQUEST['page'] . '&action=add">Add New</a></h2>';
   $mylist_table->prepare_items();
   $mylist_table->display();
   echo "</div>";
   

   i hope this is used full for you that is the dynamic class you need to display more column in $column array add column name and $data array add that name of column as key or value like this.

   $data = array(
   array("id" => 1, "name" => "Renish Khunt", "add" => "asd","newcolumn"=>"value"),
   array("id" => 2, "name" => "Renish Khunt", "add" => "asd","newcolumn"=>"value"),
   array("id" => 3, "name" => "Renish Khunt", "add" => "asd","newcolumn"=>"value")
   );
   $columns = array(
       "name" => "name",
       "add" => "add",
       "newcolumn"=>"New Column"
   );
   

   like this i hope this code is used full for you.

   thank you.
