Insert Table in Angular Markdown Editor Component

29 Aug 20259 minutes to read

To enable the table insertion feature, add the CreateTable option to the toolbar items. Once added, users can click the Insert Table icon in the toolbar to insert a table into the editor.

By default, when a table is inserted, it consists of:

  • 2 rows and 2 columns
  • A table header row

This ensures that users can start formatting and adding content immediately.

Changing default content

By default, when you insert a table, it comes with predefined column headers and structure. However, you can customize the table’s default content, including the heading and column names, to match your requirements.

The following example demonstrates how to customize the table content in the Markdown Editor:

import { Component } from '@angular/core';
import { L10n } from '@syncfusion/ej2-base';
import { RichTextEditorModule, ToolbarService, MarkdownEditorService , HtmlEditorService, ImageService, LinkService, TableService, ToolbarSettingsModel } from '@syncfusion/ej2-angular-richtexteditor';

L10n.load({
  'en-US': {
    richtexteditor: { TableHeadingText: 'Header', TableColText: 'Cell' },
  },
});

@Component({
    imports: [
        RichTextEditorModule
    ],
    standalone: true,
    selector: 'app-root',
    template: `<ejs-richtexteditor id='markdown-editor' [editorMode]='mode' [toolbarSettings]='tools' [value]="value"></ejs-richtexteditor>`,
    providers: [ToolbarService, HtmlEditorService, MarkdownEditorService, ImageService, LinkService, TableService]
})

export class AppComponent {
    public mode: string = 'Markdown';
    public value: string =
      'In Rich Text Editor, you click the toolbar buttons to format the words and the changes are visible immediately. Markdown is not like that.
