Angular PrimeNG Table pFrozenColumn Properties

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 pFrozenColumn Properties in Angular PrimeNG.

The Table component shows some data to the user in tabular form. The pFrozenColumn properties are used to freeze a column. There are two properties for the pFrozenColumn directive which are listed below:

• frozen: This is a boolean property used to state whether the column is frozen or not. 
• alignFrozen: This property defined the alignment of the frozen column. It defines whether the frozen column should stick to the left or the right of the table. The default value is left.

Syntax:

<p-table [value]="cars" [scrollable]="true" scrollDirection="horizontal">
    <ng-template pTemplate="header">
        <tr>
            <th style="width: 300px" pFrozenColumn>
                Car
            </th>
            <th style="width: 300px">Company</th>
                ...
        </tr>
    </ng-template>
    <ng-template pTemplate="body" let-car>
        <tr>
            <td style="width: 300px" pFrozenColumn>
               {{car.name}}
            </td>
            <td style="width: 300px">{{car.company}}</td>
                ...
            </tr>
    </ng-template>
</p-table>
