Angular ag-Grid:如何为字段名称不同的单元格自动生成默认模板？

npm install --save ag-grid-angular

import { Component, OnInit } from '@angular/core';
import { AgGridModule } from 'ag-grid-angular';

export class MyComponent implements OnInit {
  columnDefs = [
    { headerName: '字段1', field: 'field1' },
    { headerName: '字段2', field: 'field2' },
    { headerName: '字段3', field: 'field3' }
  ];

  rowData = [
    { field1: '值1', field2: '值2', field3: '值3' },
    { field1: '值4', field2: '值5', field3: '值6' },
    { field1: '值7', field2: '值8', field3: '值9' }
  ];

  ngOnInit() {
  }
}

<ag-grid-angular
  style="width: 500px; height: 200px;"
  class="ag-theme-alpine"
  [columnDefs]="columnDefs"
  [rowData]="rowData">
</ag-grid-angular>
