TreeByNestingTableColumn 
The TreeByNestingTableColumn element allows the integration of a tree structure in a Table. The tree structure has nodes with subordinate leaves, similar to the UI element Tree.
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.
Get and Set Selection
● Get all selected elements (including the lead selection)
selected_elements =
CL_WD_DYNAMIC_TOOL=>GET_TABLE_TREE_SELECTION(
DATA_SOURCE = context_node_of_the_data_source
).
● Get the lead selection only
lead_selection =
CL_WD_DYNAMIC_TOOL=>GET_TABLE_TREE_LEAD_SELECTION(
DATA_SOURCE = context_node_of_the_data_source
).
● Set lead selection
With including_single_selection=true all single selections and multi-selections are removed and one single selection is set to the element of the lead selection.
CL_WD_DYNAMIC_TOOL=>SET_TABLE_TREE_LEAD_SELECTION(
LEAD_SELECTION = new_lead_selection_element
DATA_SOURCE = context_node_of_the_data_source
).
● Set all selections
CL_WD_DYNAMIC_TOOL=>SET_TABLE_TREE_LEAD_SELECTION(
DATA_SOURCE = context_node_of_the_data_source
).
