Angular PrimeNG TreeTable Full Page Scroll
Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. This article will show us how to use TreeTable Full Page Scroll in Angular PrimeNG.
Angular PrimeNG TreeTable Full Page Scroll enables Full Page Viewport scroll in the TreeTable component. FlexScroll can be used for cases where the scrollable viewport should be responsive with respect to the window size. So, using a scroll, we can easily customize the TreeTable component and show Table Data according to the best user experience.
Syntax:
<div style="height: calc(100vh - 149px)"> <p-treeTable [scrollable]="true" scrollHeight='flex' > </p-treeTable> </div>
Creating Angular application & Module Installation:
Step 1: Create an Angular application using the following command.
ng new appname
Step 2: After creating your project folder i.e. appname, move to it using the following command.
cd appname
Step 3: Install PrimeNG in your given directory.
npm install primeng --save npm install primeicons --save
Project Structure: It will look like the following:
Example 1: Below is a simple example that demonstrates the use of the Angular PrimeNG TreeTable Full Page Scroll.
app.component.html
< div style = "height: calc(100vh - 149px)" > < h2 style = "color: green" >w3wiki</ h2 > < h4 >Angular PrimeNG TreeTable Full Page Scroll</ h4 > < p-treeTable [value]="tableData" [scrollable]="true" scrollHeight = "flex" > < ng-template pTemplate = "header" > < tr > < th >Name</ th > < th >Age</ th > </ tr > </ ng-template > < ng-template pTemplate = "body" let-rowNode let-row = "rowData" > < tr [ttRow]="rowNode"> < td > < p-treeTableToggler [rowNode]="rowNode"> </ p-treeTableToggler > {{ row.name }} </ td > < td >{{ row.age }}</ td > </ tr > </ ng-template > </ p-treeTable > </ div > |
app.component.ts
import { Component } from '@angular/core' ; import { NodeService } from './nodeservice' ; import { TreeNode } from 'primeng/api' ; @Component({ selector: 'app-root' , templateUrl: './app.component.html' , }) export class AppComponent { tableData: TreeNode[] = []; constructor(private nodeService: NodeService) { } ngOnInit() { this .tableData = [ { data: { name: 'David' , age: '40' , }, children: [ { data: { name: 'Nathan' , age: '16' , }, }, { data: { name: 'Shane' , age: '14' , }, }, ], }, { data: { name: 'Warner' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'Max' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'Willy' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'Miley' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'Sam' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'James' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'James' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'James' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'James' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'James' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, { data: { name: 'James' , age: '55' , }, children: [ { data: { name: 'Michelle' , age: '20' , }, }, { data: { name: 'Charlie' , age: '24' , }, }, ], }, ]; } } |

Example 2: Below is another example that demonstrates the use of the Angular PrimeNG TreeTable Full Page Scroll. In this example, we are integrating Horizontal and vertical sorting.
