# setWidth(_:ofColumn:)

Sets the width of the specified column.

## Declaration

```swift
func setWidth(_ columnWidth: CGFloat, ofColumn columnIndex: Int)
```

## Parameters

- `columnWidth`: The new width of the specified column.
- `columnIndex`: The index of the column for which to set the width.

## Discussion

Discussion This method can be used to set the initial width of browser columns unless the column sizing is automatic; setWidth(_:ofColumn:) does nothing if columnResizingType is NSBrowser.ColumnResizingType.autoColumnResizing. To set the default width for new columns (that don’t otherwise have initial widths from defaults or via the delegate), use a columnIndex of –1. A value set for columnIndex of –1 is persistent. An columnConfigurationDidChangeNotification notification is posted (not immediately), if necessary, so that the browser can autosave the new column configuration.
