# resizingMask

The table column’s resizing mask.

```
var resizingMask: NSTableColumn.ResizingOptions { get set }
```

## Discussion

The value of this property specifies the resizability of the table column. See [Resizing Modes](/documentation/AppKit/resizing-modes) for possible values. Values can be combined using the C bitwise OR operator.

When the value of this property is `0`, the column is not resizable. The default value of this property is [`userResizingMask`](/documentation/AppKit/NSTableColumn/ResizingOptions/userResizingMask) | [`autoresizingMask`](/documentation/AppKit/NSTableColumn/ResizingOptions/autoresizingMask).
