It would be great to have this feature. However, there is a really nice way to fix it. It clicks all collapse icons causing everything to fold :)

  ngAfterViewInit() {
    this.collapseRows();
  }

  collapseRows() {
    const collapsors = document.getElementsByTagName('mat-icon');
    // tslint:disable-next-line: prefer-for-of
    for (let i = 0; i < collapsors.length; i++) {
      const collapsor = collapsors[i] as HTMLElement;
      collapsor.click();
    }
  }
