This is working out well using nodes. I do have one question that I can't seem to figure out. I am using glyphs for the expand/contract symbols and they work fine with 1 fixed column. Now I want to add a row indicator in another fixed column and I want that to be in column 1 and the expand/contract glyph in column 2. I can't seem to make that happen, it appears the expand/contract glyph is always in the leftmost fixed column as is the row indicator (glyph seems to win over row indicator). Can I control what fixed column the expand/contract glyph appears?
