I pretty much have the functionality of my tree working as i want.  There is a collection of items, and if the item has no children, it is to be considered a "Difference".  If the "Difference" is checked, it is to be counted as "Accepted".  This all seems to work, but i would like to make the tree layout like this:

1) The checkbox should be under the Accepted? column, and the Accepted and Differences counts should be under their respective column headers, and the name should text wrap if it gets beyond the name column width.
