leaf.table.BCol – null colour was defaulting to white, so painted white rectangles if there were other colours given. Should be left unpainted unless you really want white (possible on web page).

leaf.table.Titles – accepts a rectangular matrix of titles (multi-row) and generates the tree-structure from this by merging like cells horizontally. Equivalent to providing a vector of titles and a depth vector, but much easier for an APL program to generate and in line with the way you specify the data for VSFlexGrid which uses cell-merging here.

leaf.table.titlegrid – tidies up the gridline drawing a little. New approach is to extend the verticals from the table upwards into the title region as far as they can go, given the tree-structured headings. This means that if you use variable-weight vertical gridlines you no longer get an unsightly join at the bottom of the title region!
