# NSTableView.DraggingDestinationFeedbackStyle.gap

Provides a gap insertion when dragging over the table. Note that this style is only officially supported for [`NSView`](/documentation/AppKit/NSView)-based table views, but may partially work in Cell Based TableViews. The decision to use the gap style (compared to another style) can be made in [`tableView(_:draggingSession:willBeginAt:forRowIndexes:)`](/documentation/AppKit/NSTableViewDataSource/tableView(_:draggingSession:willBeginAt:forRowIndexes:)), or it can dynamically be changed.
