CKEditor 5：将表功能添加到classic-build失败

Question

我正在使用CKEditor 5，经典编辑器，我想在工具栏中添加表格功能，我使用webpack来管理依赖项，这里是我的代码：

   import ClassicEditor from "@ckeditor/ckeditor5-build-classic/build/ckeditor";   
   import Table from '@ckeditor/ckeditor5-table/src/table';
   import TableToolbar from '@ckeditor/ckeditor5-table/src/tabletoolbar';


   $('.ckEditorArea').each(function () {

   ClassicEditor
        .create(this, {
            plugins: [ Table, TableToolbar ],
            toolbar: ['insertTable' ],
            table: {
                toolbar: [ 'tableColumn', 'tableRow', 'mergeTableCells' ]
            }
        } )
        .then( editor => {
            console.log( 'Editor was initialized', editor );
        } )
        .catch( error => {
            console.error( error.stack );
        } );
  )};

我添加了包裹：

    npm install --save @ckeditor/ckeditor5-table

然后我重建我的项目：

npm run build

我在导航器控制台中出现此错误：

这时我执行命令

npm run build

结果：
