在内置Angular后显示黑色三角形的CkEditor？

import { CKEditorModule } from '@ckeditor/ckeditor5-angular';

@NgModule({
  imports: [
    // ...
    CKEditorModule
  ],
  // ...
})
export class YourComponentModule { }

<ckeditor [editor]="Editor" [config]="editorConfig" [(ngModel)]="editorData"></ckeditor>

import * as ClassicEditor from '@ckeditor/ckeditor5-build-classic';

@Component({
  // ...
})
export class YourComponent implements OnInit {
  public Editor = ClassicEditor;
  public editorData = '<p>初始内容</p>';
  public editorConfig = {
    toolbar: {
      items: [
        'heading',
        '|',
        'bold',
        'italic',
        'link',
        'bulletedList',
        'numberedList',
        'blockQuote',
        'insertTable',
        'undo',
        'redo'
      ]
    },
    language: 'zh-cn',
    // 更多配置项...
  };

  // ...
}
