Angular PrimeNG Table Cell Editing

Last Updated : 23 Jul, 2025

Angular PrimeNG is an open-source library that consists of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. In this article, we will see Angular PrimeNG Table Cell Editing.

The Table Component is used to show some data to the user in the tabular form. Cell editing in a table can be enabled by adding the pEditableColumn directive to a cell that has a p-cellEditor component with input-output templates.

Syntax:

<p-table [value]="books" responsiveLayout="scroll">
    <ng-template pTemplate="header">
        <tr>
            <th>Name</th>
            ...
        </tr>
    </ng-template>
    <ng-template pTemplate="body" 
        let-book 
        let-rowData 
        let-x="rowIndex">
        <tr>
            <td pEditableColumn>
                <p-cellEditor>
                    <ng-template pTemplate="input">
                        <input 
                            pInputText 
                            type="text" 
                            [(ngModel)]="rowData.name">
                    </ng-template>
                    <ng-template pTemplate="output">
                        {{rowData.name}}
                    </ng-template>
                </p-cellEditor>
            </td>
            ...
        </tr>
    </ng-template>
</p-table>

Creating Angular application and Installing the Modules:

Step 1: Create an Angular application using the following command.

ng new myapp

Step 2: After creating your project folder i.e. myapp, move to it using the following command.

cd myapp

Step 3: Install PrimeNG in your given directory.

npm install primeng --save
npm install primeicons --save

Project Structure: After completing the above steps the project structure will look like the following.

Run the Application:

ng serve --open

Example 1: This example shows how to enable cell editing in a simple table.
