Angular PrimeNG TreeTable - Responsive

Last Updated : 28 Sep, 2022

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 Column Resize in Angular PrimeNG.

Angular PrimeNG TreeTable Responsive is used to make the TreeTable component responsive so that it could be perfect for all screen sizes. It makes the TreeTable component more interactive.

Syntax:

<ng-template pTemplate="emptymessage" let-columns>    <tr>       <td [attr.colspan]="columns.length">           No records found       </td>     </tr>  </ng-template>

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 example demonstrates the use of the Angular PrimeNG TreeTable Responsive.
