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. It provides a lot of templates, components, theme design, an extensive icon library, and much more. In this article, we will see the Angular PrimeNG Table Column Toggle Component.

The Table Component is used to display tabular data. PrimeNG provides a lot of customization in properties, methods, templates, and styling to make the component look and function as required. The Table component can also be made dynamic so that the data can be loaded efficiently.

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 primeicons --save

Project Structure: It will look like the following:

 

Steps to run the application: To run the above file run the below command:

ng serve --save

Example 1: This is the basic example that shows how to use the Angular PrimeNG Table Column Toggle using the header filter to the left side.
