I recall this hasn't been done but like to make sure. With now the Tree
widget supporting multiple columns and thus making TableTree class
depreciated, is there an equivalent viewer support of TableTreeViewer from
jface side, or will I need to construct and update the TreeItem nodes
manually? Thanks.
