# allowsColumnReordering

A Boolean value indicating whether the table view allows the user to rearrange columns by dragging their headers.

```
var allowsColumnReordering: Bool { get set }
```

## Discussion

The default value of this property is <doc://com.apple.documentation/documentation/Swift/true>, which allows the user to rearrange the table view’s columns. You can rearrange columns programmatically regardless of this setting.
