Angular 17 Multi level Tree Grid. Simple, Light Weight and dependency free. Basically it groups data by a field or multiple fields. For hierarchical data (where there is a Parent-Child relationship), check out this
Angular Tree Grid Package. If header needs to be fixed/freezed and body needs to be scrollable then check out this Angular Fix Header Grid Package.
