- app.component.ts
Javascript
import { Component } from '@angular/core' ; interface People { firstname?: string; lastname?: string; age?: string; } @Component({ selector: 'app-root' , templateUrl: './app.component.html' , }) export class AppComponent { tableData: People[] = []; cols: any[] = []; constructor() { } ngOnInit() { this .cols = [ { field: 'firstname' , header: 'First Name' }, { field: 'lastname' , header: 'Last Name' }, { field: 'age' , header: 'Age' }, ]; this .tableData = [ { firstname: 'David' , lastname: 'ace' , age: '40' , }, { firstname: 'AJne' , lastname: 'west' , age: '40' , }, { firstname: 'Mak' , lastname: 'Lame' , age: '40' , }, { firstname: 'Peter' , lastname: 'raw' , age: '40' , }, { firstname: 'Kane' , lastname: 'James' , age: '40' , }, { firstname: 'Peter' , lastname: 'raw' , age: '40' , }, { firstname: 'Kane' , lastname: 'James' , age: '40' , }, { firstname: 'Peter' , lastname: 'raw' , age: '40' , }, { firstname: 'Kane' , lastname: 'James' , age: '40' , }, { firstname: 'Peter' , lastname: 'raw' , age: '40' , }, { firstname: 'Kane' , lastname: 'James' , age: '40' , }, { firstname: 'Peter' , lastname: 'raw' , age: '40' , }, { firstname: 'Kane' , lastname: 'James' , age: '40' , }, ]; } } |
