TreeByKeyTableColumn 
The TreeByKeyTableColumn element allows the integration of a tree structure in a Table. It is displayed exactly the same as a TreeByKeyTableColumn element, but is implemented using the parent key relationship.
Note that the properties isLeaf, expanded, parentKey, and rowKey must be bound to the attributes of dataSource. The binding to subnodes of dataSource is not permitted here because this would affect performance.
Unlike the Tree the UI elements for the hierarchical table enable:
● User entries
● Scrolling
● Search with selection of the next hit using the toolbar
