Takes a plain html table and turns it into a treetable. Uses jQuery, so you get all the functionality of this wonderful library for free. Update Dec 2008 Feature Set:- Has now been fully updated to work with JQuery 1.2+ Multiple treetables in the one page - new Optionally uses a cookie to remember the state across page refreshes and as parent nodes are collapsed/expanded - new Highlighting as you hover over rows. Dynamic striping. Set tree to any column of the table. Collapse certain nodes initially. Connecting lines. Very fast, even on large datasets. Can have other content in the same table not part of the tree. ~14kb zipped inc images and examples etc.
