Angular material table not showing data until I click paging links - datatable

Question

I followed stackblitz MatDataTable. The table is not populating until i click pagination links. After clicking pagination everything works normal.I am trying since last day. I tried this stackoverflow solution as well but didn't workde:
table.component.ts
import { Component, OnInit, ViewChild } from '#angular/core';
import { MatPaginator, MatTableDataSource } from '#angular/material';
#Component({
selector: 'app-table',
templateUrl: './table.component.html',
styleUrls: ['./table.component.scss']
})
export class TableComponent implements OnInit {
displayedColumns: string[] = ['position', 'name', 'weight', 'symbol'];
dataSource = new MatTableDataSource<PeriodicElement>(ELEMENT_DATA);
#ViewChild(MatPaginator) paginator: MatPaginator;
ngOnInit() {
this.dataSource.paginator = this.paginator;
}
}
export interface PeriodicElement {
name: string;
position: number;
weight: number;
symbol: string;
}
const ELEMENT_DATA: PeriodicElement[] = [
{position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H'},
{position: 2, name: 'Helium', weight: 4.0026, symbol: 'He'},
{position: 3, name: 'Lithium', weight: 6.941, symbol: 'Li'},
{position: 4, name: 'Beryllium', weight: 9.0122, symbol: 'Be'},
{position: 5, name: 'Boron', weight: 10.811, symbol: 'B'},
{position: 6, name: 'Carbon', weight: 12.0107, symbol: 'C'},
{position: 7, name: 'Nitrogen', weight: 14.0067, symbol: 'N'},
{position: 8, name: 'Oxygen', weight: 15.9994, symbol: 'O'}
];
table.component.html
Copied same data from here. and removed the table, tr, th and td tags. as per google suggestion.
<div class="mat-elevation-z8">
<mat-table [dataSource]="dataSource">
<!-- Position Column -->
<ng-container matColumnDef="position">
<mat-header-cell *matHeaderCellDef> No. </mat-header-cell>
<mat-cell *matCellDef="let element"> {{element.position}} </mat-cell>
</ng-container>
<!-- Name Column -->
<ng-container matColumnDef="name">
<mat-header-cell *matHeaderCellDef> Name </mat-header-cell>
<mat-cell *matCellDef="let element"> {{element.name}} </mat-cell>
</ng-container>

<ng-container matColumnDef="weight">
<mat-header-cell *matHeaderCellDef> Weight </mat-header-cell>

Answer 1

Initialise pagination on ngAfterViewInit hooks lifecycle
here's example,
ngAfterViewInit() {
this.dataSource.paginator = this.paginator;
}
You are using paginator on onInit(), remove from onInit()
