Angular PrimeNG Table Edit

Last Updated : 29 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 Edit in Angular PrimeNG.

Angular PrimeNG Table Edit enables Editing the Table cells in the Table component. So using the Edit feature, we can easily edit the Table component data easily.

Syntax:

<p-table>
  <td pEditableColumn>
     <p-cellEditor>
         <ng-template pTemplate="input">
            <input pInputText type="text" 
                   [(ngModel)]="product.code" disabled>
        </ng-template>
        <ng-template pTemplate="output">
            {{product.code}}
        </ng-template>
     </p-cellEditor>
  </td>
</p-treeTable>

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 demonstrating the use of the Angular PrimeNG Table Edit, where we have to use p-treeTableCellEditor to make the cells editable.
