p-tableCheckbox check by default

I'm new with primeNG and p-tableCheckbox. I'm using this component to create a checkbox column to check/select the right row. So the normal standard and behaviour works perfectly. But now I need to select by default some row/checkoxes by component.ts.

I'm searching everywhere and I don't find anything about this behaviour.

I tried something like this

<p-tableCheckbox #tableCheckbox [value]="rowData" [index]="rowIndex"></p-tableCheckbox>
