Question

Is there a way to retrieve the current page index from a PrimeNG table?

I love using the PrimeNg library and am currently working with the Table component that has paginator functionality enabled. In my Django backend application, I am utilizing the PageNumberPagination. Now, the challenge I am facing is how to retrieve the current page number from this component?

<p-table
    [value]="rows"
    [paginator]="true"
    [rows]="10"
></p-table>

@Component({
    selector: 'app-table',
    templateUrl: 'table.html',
    standalone: true,
    imports: [TableModule, CommonModule],
    providers: [ApiService]
})
export class TablePaginatorBasicDemo {
    rows!: Row[];

    constructor(private apiService: ApiService) {}

    ngOnInit() {
        this.apiService.getRows().pipe(tap((rows) => ({this.rows = rows}))).subscribe();
    }
}

Here is a suggestion to address your issue:

component.ts:

  readonly ITEMS_PER_PAGE = 10;
  currentPageIndex = 0;

  updateCurrentPageIndex(firstItemIndex: number): void {
    this.currentPageIndex = firstItemIndex / this.ITEMS_PER_PAGE;
    console.log('current page index has been updated to: ', this.currentPageIndex + 1);
  }

component.template.html:

 <p-table
   responsiveLayout="scroll"
   [value]="itemsList"
   [paginator]="true"
   [rows]="ITEMS_PER_PAGE"
   (firstChange)="updateCurrentPageIndex($event)"
 >

this.currentPageIndex stores the current page index (starting at 0).
