How do you customize the drop highlight for a NSTableView?

The highlighting I want is for it to draw the drop indicator between rows and to never highlight an entire row. How can I do this with the 10.5 SDK?

Since I am using the 10.5 SDK, I don't have access to -setDraggingDestinationFeedbackStyle: which is available in the 10.6 SDK.

You need to implement the ‑tableView:validateDrop:proposedRow:proposedDropOperation: table datasource method and return NSTableViewDropAbove rather than NSTableViewDropOn for the rows in question.

As per the docs, to propose a drop below the last row, row would be [aTableView numberOfRows] and operation would be NSTableViewDropAbove.
