如何在使用ngx格式构建的datatable中选择行

<ngx-datatable
  [rows]="data"
  [columns]="columns"
  [selectionType]="'single'"
  (selected)="onSelect($event)">
</ngx-datatable>

import { Component } from '@angular/core';

@Component({
  selector: 'app-datatable',
  templateUrl: './datatable.component.html',
  styleUrls: ['./datatable.component.css']
})
export class DatatableComponent {
  data = [
    { name: 'John', age: 25 },
    { name: 'Jane', age: 30 },
    { name: 'Bob', age: 35 }
  ];

  columns = [
    { prop: 'name', name: 'Name' },
    { prop: 'age', name: 'Age' }
  ];

  onSelect(event) {
    // 处理选择行的逻辑
    console.log(event.selected);
  }
}
