There is no sin is using less than all the features of a widget.
Anyway, think of the tree having one node, which you can hide (not
show), representing the table, and n leaves, representing the rows of
the table, which you do show.
If you sort the selection by some categorical field, then you can make
the display hierarchical by adding expandable rows for values of the
sort field. Think of database reports where summary lines can be
expanded and contracted.
