How to hide column in PrimeNG turbo table?

Question

Hi I am trying to convert my PrimeNG data-table to turbo table. Actually I have used [hidden]="!cols.visibility" in PrimeNG my data-table. Now what I should used to achieve the same in turbo table.

Previous datatable Column Code :

<p-column *ngFor="let col of cols"  [hidden]="!col.visibility" [field]="col.field" [header]="col.header"></p-column>

● Documentation URL: https://www.primefaces.org/primeng/#/datatable

New Turbo table Column Code :

<ng-template pTemplate="header" let-cols>
      <tr>
          <th style="width: 2.25em"></th>
          <th *ngFor="let col of cols">
              {{col.header}}
          </th>
      </tr>
  </ng-template>

● Documentation URL : https://www.primefaces.org/primeng/#/table

What should I use ? I have checked documentation as well but didn't find solution.

We have a similar requirement where we need to hide/show columns dynamically, but also maintain the order of the columns. Here's how we've written the code:

Table definition:

<p-table [columns]="columns">
    <ng-template pTemplate="header" let-columns>
        <tr>
            <th *ngFor="let column of columns" [ngStyle]="{'display': column.display}">
                {{ column.header }}
            </th>
        </tr>
    </ng-template>

    <ng-template pTemplate="body" let-rowData let-columns="columns">
        <tr>
            <td *ngFor="let column of columns" [ngStyle]="{'display': column.display}">
                {{ rowData[column.field }}
            </td>
        </tr>
    </ng-template>
</p-table>

Column definition:

this.columns = [
    {
        field: 'test'
        header: 'Test Header'
        display: 'table-cell'
    },
    {
        field: 'hiddenTest'
        header: 'Hidden Column'
        display: 'none'
    }
];

This will enable you to iterate the array of columns and dynamically change the inline style from 'table-cell' to 'none' and back without changing the original order of the columns.
