Answer 1

For me, nothing of these answers didn't work. I had an observable that I subscribe to get new data. the only solution that works for me was:

 this.dataService.pointsNodesObservable.subscribe((data) => {
  this.dataSource = new InsertionTableDataSource(this.paginator, this.sort, this.dataService);
  this.dataSource.data = data;
});

render like a charm!
