如何使用指令为KendoGrid的[columnMenu]设置默认设置？

Question

我创建了一个Angular指令来为KendoGrid设置默认设置。我设置了可排序，可调整大小，可过滤和可重新排序的属性，并且效果很好。我尝试为[columnMenu]设置默认设置时遇到问题。设置将被完全忽略。

// -----------------------------
// default-settings.directive.ts
// -----------------------------
import { Directive, OnInit } from '@angular/core';
import { GridComponent, ColumnMenuSettings } from '@progress/kendo-angular-grid';

@Directive({
  selector: '[appDefaultSettings]'
})
export class DefaultSettingsDirective implements OnInit {

  defaultColumnMenu: ColumnMenuSettings = {
    sort: false,
    filter: false,
    lock: false,
    columnChooser: true
  }
  sortable: boolean = true;
  resizable: boolean = true;
  filterable: boolean = true;
  reorderable: boolean = true;

  constructor(
    private grid: GridComponent,
  ) { }

  private initializeDefaults() {
    this.grid.sortable = this.sortable;
    this.grid.resizable = this.resizable;
    this.grid.filterable = this.filterable;
    this.grid.reorderable = this.reorderable;
    this.grid.columnMenu = this.defaultColumnMenu;    
  }

  ngOnInit(): void {
    this.initializeDefaults();
  }
}

// -----------------------------
// app.component.ts
// -----------------------------
import { Component } from '@angular/core';
import { customers } from './customers';

@Component({
    selector: 'my-app',
    template: `
        <kendo-grid appDefaultSettings
          [kendoGridBinding]="data"
          [height]="410">
        </kendo-grid>
    `
})
export class AppComponent {
    public data: any[] = customers;
    constructor() {
    }
}

这里是StackBlitz link的完整示例。
