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

It's trying to sort by element['project.name']. Obviously element doesn't have such a property.

It should be easy to create a custom datasource that extends MatTableDatasource and supports sorting by nested object properties. Check out the examples in material.angular.io docs on using a custom source.
