将 Angular Datatable 与 DataTables 按钮扩展一起使用，但 dt-button-collection 附加在正文的末尾，为什么？

关于 css/js 存在一些问题。

我该如何解决这个错误？这是我的代码。

dtOptions: any = {};
dtTrigger: any = new Subject();

ngOnInit() {
  this.dtOptions = {
    pagingType: 'full_numbers',
    pageLength: 10,
    dom: 'Blfrtip',
    buttons: [{
        extend: 'collection',
        text: 'Export Data',
        className: 'exp_d_btn',

        buttons: [{
            extend: 'excel',
            text: '<img src="assets/images/xls.png" width="24">&nbsp; XLS',
            exportOptions: {
              columns: ':visible'
            }
          },
          {
            extend: 'pdf',
            text: '<img src="assets/images/pdf-mis.png" width="24"> &nbsp;PDF',
            exportOptions: {
              columns: ':visible'
            },
            orientation: 'landscape'
          },
          {
            extend: 'csv',
            text: '<img src="assets/images/csv.png" width="24">&nbsp; CSV',
            exportOptions: {
              columns: ':visible'
            }
          },

        ]
      }

    ]
  };
}
<table datatable [dtOptions]="dtOptions" [dtTrigger]="dtTrigger" class="table" id="grid">
  <thead>
    <tr>head1
    </tr>
    <tr>head2
    </tr>
  </thead>
  <tbody>
    <tr *ngFor="let val of tableData">
      <td>{{val.val1}}</td>
      <td>{{val.val2}}</td>
    </tr>
  </tbody>
</table>

这是我正在使用angular.json文件的依赖项

dt-button-collection在末尾追加 在此处输入图像描述

并在单击导出按钮时出现此错误在此处输入图像描述

这是package.json文件

我在这里做错了什么？是版本问题吗？
