DataTables 复选框无法正确显示

Question

我已经创建了 jQuery 个 DataTables 复选框，现在我的问题是我无法在数据 table 中向 select 显示多个复选框。我试图为 jQuery DataTables 库添加一个复选框扩展，它提供了一个通用的解决方案来处理 table 中的复选框。但错误显示消息是 Script error 希望有人能指出我遇到的错误。谢谢

下面是我的示例代码：

$(document).ready(function() {
   var table = $('#example').DataTable({     
      'columnDefs': [
         {
            'targets': 0,
            'checkboxes': {
               'selectRow': true
            }
         }
      ],
      'select': {
         'style': 'multi'
      },
      'order': [[1, 'asc']]
   });
   
   // Handle form submission event 
   $('#frm-example').on('submit', function(e){
      var form = this;
      
      var rows_selected = table.column(0).checkboxes.selected();

      // Iterate over all selected checkboxes
      $.each(rows_selected, function(index, rowId){
         // Create a hidden element 
         $(form).append(
             $('<input>')
                .attr('type', 'hidden')
                .attr('name', 'id[]')
                .val(rowId)
         );
      });

     
      
      // Output form data to a console     
      $('#example-console-rows').text(rows_selected.join(","));
      
      // Output form data to a console     
      $('#example-console-form').text($(form).serialize());
       
      // Remove added elements
      $('input[name="id\[\]"]', form).remove();
       
      // Prevent actual form submission
      e.preventDefault();
   });   
});

         <th></th>
         <th>Name</th>

         <th>Age</th>

   </tfoot>
</table>

这是我的预期结果：

此代码有效。

$(document).ready(function() {
   var table = $('#example').DataTable({     
      'columnDefs': [
         {
            'targets': 0,
            'checkboxes': {
               'selectRow': true
            }
         }
      ],
      'select': {
         'style': 'multi'
      },
      'order': [[1, 'asc']]
   });
   
   // Handle form submission event 
   $('#frm-example').on('submit', function(e){
      var form = this;
      
      var rows_selected = table.column(0).checkboxes.selected();

      // Iterate over all selected checkboxes
      $.each(rows_selected, function(index, rowId){
         // Create a hidden element 
         $(form).append(
