# outlineView(_:didRemove:forRow:)

Implemented to know when a row view is removed from the table

## Declaration

```swift
@MainActor optional func outlineView(_ outlineView: NSOutlineView, didRemove rowView: NSTableRowView, forRow row: Int)
```

## Parameters

- `outlineView`: The outline view that sent the message.
- `rowView`: The row view that was removed.
- `row`: The number of the row that was removed due to being moved offscreen, or -1 if the row was removed from the table so it is no longer valid.

## Discussion

Discussion The removed rowView may be reused by the table, so any additionally inserted views should be removed at this point.
