Pagination In Matrial Table With Angular

When we have a huge number of records in the table, it is difficult to see the complete table data. In such circumstances, we employ a straightforward navigation technique known as Pagination.

Pagination is simply the process of separating a large number of items in a table into smaller portions or pages.

Step 1:

Create angular application

ng g c material-table

Step 2:

Add Following Package

ng add @angular/material

Step 3:

Include the MatTableModule and MatSortModule in your app. The module.ts file

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { MatTableModule } from '@angular/material/table';
import { MatPaginatorModule } from '@angular/material/paginator';
   
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    MatTableModule,
    MatPaginatorModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Step 4:

Insert the following code into your app.component.ts file.

import {Component, OnInit, ViewChild} from '@angular/core';
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'}
];
/**
 * @title Table with sorting
 */
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent implements OnInit {
  displayedColumns: string[] = ['position', 'name', 'weight', 'symbol'];
  dataSource = new MatTableDataSource<PeriodicElement>(ELEMENT_DATA);

  @ViewChild(MatPaginator) paginator: MatPaginator;

  ngAfterViewInit() {
    this.dataSource.paginator = this.paginator;
  }
}

Step 5 :

Insert the following code into your app.component.html file

<div class="mat-elevation-z8">
  <table mat-table [dataSource]="dataSource">

    <!-- Position Column -->
    <ng-container matColumnDef="position">
      <th mat-header-cell *matHeaderCellDef> No. </th>
      <td mat-cell *matCellDef="let element"> {{element.position}} </td>
    </ng-container>

    <!-- Name Column -->
    <ng-container matColumnDef="name">
      <th mat-header-cell *matHeaderCellDef> Name </th>
      <td mat-cell *matCellDef="let element"> {{element.name}} </td>
    </ng-container>

    <!-- Weight Column -->
    <ng-container matColumnDef="weight">
      <th mat-header-cell *matHeaderCellDef> Weight </th>
      <td mat-cell *matCellDef="let element"> {{element.weight}} </td>
    </ng-container>

    <!-- Symbol Column -->
    <ng-container matColumnDef="symbol">
      <th mat-header-cell *matHeaderCellDef> Symbol </th>
      <td mat-cell *matCellDef="let element"> {{element.symbol}} </td>
    </ng-container>

    <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
    <tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
  </table>

  <mat-paginator [pageSizeOptions]="[5, 10, 20]"
                 showFirstLastButtons 
                 aria-label="Select page of periodic elements">
  </mat-paginator>
</div>

Step 6:

Run your Application using the following code

ng serve
