Angular PrimeNG Table Selection

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 Table Filtering in Angular PrimeNG.

Angular PrimeNG Table Selection enables single and multiple node selection modes in the Table component so that we can select single or multiple table nodes at once. So, using table selection, we can make the table more user-friendly and efficient.



Angular PrimeNG Table Selection properties:

Syntax:



<p-table 
    #tableref
    selectionMode="single | multiple">
    
      <ng-template pTemplate="body">
        <tr [pSelectableRow]="row">
            ...
        </tr>
      </ng-template>
</p-table>

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:
