Use

Tables can represent a hierarchy using the ( ROW_ARRANGEMENT ( Add RowArrangement ). There are several types of this aggregation, which differ with regard to the structure of the dataSource:

  • TreeByKeyTableColumn

    The dataSource is a flat node, meaning that the hierarchy is displayed using the parent to key relationship.

  • TreeByNestingTableColumn

    The dataSource is a recursive node whose subnodes contain lower-level elements.

These two types of hierarchical table have the same appearance.

RowArrangement in a Table

There is also a third type of ROW_ARRANGEMENT aggregation: TableRowGrouping. However, it has a completely different appearance to the two ROW_ARRANGEMENT types described above.
