# NSTableView.DropOperation

NSTableView defines these constants to specify drop operations.

## Declaration

```swift
enum DropOperation
```

## Overview

Overview For example, given a table with n rows (numbered with row 0 at the top visually), a row of n–1 and operation of NSTableViewDropOn would specify a drop on the last row. To specify a drop below the last row, you use a row of n and NSTableViewDropAbove for the operation.
