Angular Material 2 DataTable Sorting with nested objects

Question

I have a normal Angular Material 2 DataTable with sort headers. All sort are headers work fine. Except for the one with an object as value. These doesn\'t sort at all.

Answer 1

I had the same issue, by testing the first proposition I had some errors, I could fixe it by adding "switch (property)"

this.dataSource.sortingDataAccessor =(item, property) => {
    switch (property) {
    case 'project.name': return item.project.name;

    default: return item[property];
    }
  };
