Angular PrimeNG TreeTable Reorder
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 Column Resize in Angular PrimeNG.
Angular PrimeNG TreeTable Reorder enables the reordering of columns in the TreeTable component. Columns can be reordered according to the user’s needs which makes the table More Interactive and user-friendly.
Syntax:
<p-treeTable
[value]="tableData"
[columns]="cols"
[reorderableColumns]="true"
>
<ng-template pTemplate="header" let-columns>
<tr>
<th *ngFor="let col of columns"
ttReorderableColumn>
{{ col.header }}
</th>
</tr>
</ng-template>
</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 Reorder.

Example 2: Below is a simple example that demonstrates the use of the Angular PrimeNG TreeTable Reorder, In this example, we are applying column reordering to scrollable data.
