# tableView(_:shouldTrackCell:for:row:)

Asks the delegate whether the specified cell should be tracked.

## Declaration

```swift
@MainActor optional func tableView(_ tableView: NSTableView, shouldTrackCell cell: NSCell, for tableColumn: NSTableColumn?, row: Int) -> Bool
```

## Parameters

- `tableView`: The table view that sent the message.
- `cell`: The cell to track.
- `tableColumn`: The table column.
- `row`: A row in tableView.

## Return Value

Return Value true if the cell should be tracked, false otherwise.

## Discussion

Discussion In general, only selectable or selected cells can be tracked. If you implement this method, cells that aren’t selectable or selected can be tracked; similarly, cells that are selectable or selected can be set as untracked. For example, this allows you to have an NSButtonCell object in a table that doesn’t change the selection, but can still be clicked on and tracked. note: This method is only valid for NSCell-based table views.
