# setDropRow(_:dropOperation:)

Retargets the proposed drop operation.

## Declaration

```swift
func setDropRow(_ row: Int, dropOperation: NSTableView.DropOperation)
```

## Parameters

- `row`: The target row index.
- `dropOperation`: The drop operation. Supported values are specified by doc://com.apple.appkit/documentation/AppKit/NSTableView/DropOperation.

## Discussion

Discussion For example, to specify a drop on the second row, specify row as 1, and operation as NSTableViewDropOn. To specify a drop below the last row, specify row as [self numberOfRows] and operation as NSTableViewDropAbove. Passing a value of –1 for row and NSTableViewDropOn as the operation causes the entire table view to be highlighted rather than a specific row. This is useful if the data displayed by the table view does not allow the user to drop items at a specific row location.
