# hideRows(at:withAnimation:)

Hides the specified table rows.

```
func hideRows(at indexes: IndexSet, withAnimation rowAnimation: NSTableView.AnimationOptions = [])
```

## Parameters

`indexes`

An index set containing indexes of the rows to be hidden.

`rowAnimation`

An animation effect to be applied when the rows are hidden.

## Discussion

Use this method when you no longer want the data to be visible to the user, but you don’t want to permanently remove the data. Hidden table rows have a height of zero and cannot be selected by the user. However, if a selected table row is hidden, it will remain selected.

Hiding a table row causes the [`tableView(_:didRemove:forRow:)`](/documentation/AppKit/NSTableViewDelegate/tableView(_:didRemove:forRow:)) delegate method to be invoked.

## See Also

[`AnimationOptions`](/documentation/AppKit/NSTableView/AnimationOptions)

Specifies the animation effects to apply when inserting or removing rows.

[`-  tableView:didRemoveRowView:forRow:`](/documentation/AppKit/NSTableViewDelegate/tableView(_:didRemove:forRow:))

Tells the delegate that a row view was removed from the table at the specified row.
