# NSTableView.DraggingDestinationFeedbackStyle.gap

Provides a gap insertion when dragging over the table. Note that this style is only officially supported for 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:), or it can dynamically be changed.

## Declaration

```swift
case gap
```
