(Although I've seen multiple requests for > variable row height tables, I've not seen a single request for > variable row height trees.) We have implemented our own tree line display here on top of tables and use images that are given appropriate vertical and horizontal sizes. The vertical line is drawn using an image 2 pixels across by 1 down, and the horizontal line is drawn using a 1 x 1 image. Our data structures and server setup allow us to draw the correct lines without loading the complete dataset from the server, so we can implement extremely efficient views onto a very large tree structure and still draw the lines.
