Angular Tree Grid to show hierarchical data. Basically if data has Parent-Child relationship. It also supports sub-grid/nested-grid. If data needs to be grouped by fields then check out this ngtreegrid Package. If header needs to be fixed/freezed and body needs to be scrollable then check out this Fix Header Grid Package.
