Angular Material 2 DataTable Sorting with nested objects

by

It was hard to find documentation on this, but it is possible by using sortingDataAccessor and a switch statement. For example:

@ViewChild(MatSort) sort: MatSort;

ngOnInit() {
  this.dataSource = new MatTableDataSource(yourData);
  this.dataSource.sortingDataAccessor = (item, property) => {
    switch(property) {
      case 'project.name': return item.project.name;
      default: return item[property];
    }
  };
  this.dataSource.sort = sort;
}
