[Solved] Angular 2 *ngFor does not print to table , I am getting my information from a GET HTTP call and it works

you can use async pipe, you dont have to subscribe to your Observable,

component.ts:

export class FormationsComponent {
  formations: Observable<Formation[]>;
  constructor(private formationService: FormationService){};

  ngOnInit() {
     this.formations = this.formationService.getFormations();
   }
}

and in your html file 

<tr *ngFor="let formation of formations | async" >
