Angular PrimeNG TreeTable Size

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 Size in Angular PrimeNG.

Angular PrimeNG TreeTable Size is used to set the size of the TreeTable component. So using the Size feature, we can easily resize the TreeTable component.

Syntax:

<p-treeTable styleClass="sizevalue">
</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 that demonstrates the use of the Angular PrimeNG TreeTable size. In this example, we are implementing small sized TreeTable.

app.component.html

<p-treeTable #myTab [columns]="cols"
             [value]="tableData"
