When developing Angular applications, presenting data in a well-structured manner is crucial. One effective way to achieve this is by utilizing tables. PrimeNG, a popular library for Angular UI components, offers a powerful and versatile data table component that can significantly enhance your application's user interface. In this article, we will explore the features of the PrimeNG Angular Table, its implementation, and how it can be customized to fit your needs.
What is PrimeNG?
PrimeNG is an open-source UI component library specifically designed for Angular applications. It provides a rich set of UI components, including forms, charts, overlays, and tables, allowing developers to create responsive and appealing user interfaces effortlessly. The PrimeNG Table component stands out because of its extensive features and flexibility in displaying data.
Original Problem Scenario
Let's consider a situation where you want to create a simple Angular application that displays a list of users in a table format. Here is an initial code snippet for a basic Angular component using PrimeNG Table:
import { Component } from '@angular/core';
@Component({
selector: 'app-user-table',
template: `
<p-table [value]="users">
<ng-template pTemplate="header">
<tr>
<th>Name</th>
<th>Email</th>
</tr>
</ng-template>
<ng-template pTemplate="body" let-user>
<tr>
<td>{{ user.name }}</td>
<td>{{ user.email }}</td>
</tr>
</ng-template>
</p-table>
`
})
export class UserTableComponent {
users = [
{ name: 'John Doe', email: '[email protected]' },
{ name: 'Jane Smith', email: '[email protected]' }
];
}
Enhancing the Table Component
While the above code sets up a basic table, PrimeNG Table offers a plethora of features, including sorting, filtering, pagination, and much more. Let's delve into how we can enhance our user table.
Adding Features
- Sorting: Allow users to sort the data by clicking the column headers.
- Filtering: Implement filters to narrow down the list based on user input.
- Pagination: Break down large datasets into manageable pages.
Here's how you can implement these features:
import { Component } from '@angular/core';
@Component({
selector: 'app-user-table',
template: `
<p-table [value]="users" [paginator]="true" [rows]="5" [sortMode]="'multiple'">
<ng-template pTemplate="header">
<tr>
<th pSortableColumn="name">Name <p-sortIcon [field]="'name'"></p-sortIcon></th>
<th pSortableColumn="email">Email <p-sortIcon [field]="'email'"></p-sortIcon></th>
</tr>
</ng-template>
<ng-template pTemplate="body" let-user>
<tr>
<td>{{ user.name }}</td>
<td>{{ user.email }}</td>
</tr>
</ng-template>
</p-table>
`
})
export class UserTableComponent {
users = [
{ name: 'John Doe', email: '[email protected]' },
{ name: 'Jane Smith', email: '[email protected]' },
// more user data
];
}
Key Features of PrimeNG Table
- Customizable Header and Body Templates: Use Angular directives to create custom headers and content.

Here is how you can implement a simple filter for the name column:
<p-table [value]="users" [paginator]="true" [rows]="5">
<ng-template pTemplate="header">
<tr>
<th>
Name
<input type="text" pInputText (input)="dt.filter($event.target.value, 'name', 'contains')" placeholder="Search by name">
</th>
<th>Email</th>
</tr>
</ng-template>
<ng-template pTemplate="body" let-user>
<tr>

</tr>
</ng-template>
</p-table>
