# tableView(_:updateDraggingItemsForDrag:)

Implement this method to allow the table to update dragging items as they are dragged over a view.

## Declaration

```swift
@MainActor optional func tableView(_ tableView: NSTableView, updateDraggingItemsForDrag draggingInfo: any NSDraggingInfo)
```

## Parameters

- `tableView`: The table view.
- `draggingInfo`: The dragging information.

## Discussion

Discussion Required for multi-image dragging. Typically this will involve invoking enumerateDraggingItems(options:for:classes:searchOptions:using:) on the draggingInfo parameter value and setting the draggingItem object’s imageComponentsProvider to a proper image based on the content. For view-based table views, you can use the NSTableCellView method draggingImageComponents. For cell-based tables, use the NSCell method draggingImageComponents(withFrame:in:).
