Default row selection for dataTable primeNG

Question

How could I select automatically a row in dataTable after a given record? The dataTable has sorted column, and pagination. After a given record I would expect the record to be selected on the page that exists.

Answer 1

The dataTable has a property(an array) called [(selection)], to add/remove/preselect rows you can just add/remove values from your array

to pre-select the nth:

component:

 ngOnInit() {
   this.data = [/*data*/];           
   this.selectedItems = [ this.data[n-1]];
 }

template:

<p-dataTable [value]="data" [(selection)]="selectedItems">
