# removeColumn(_:)

Removes the specified column at from the receiver.

## Declaration

```swift
func removeColumn(_ col: Int)
```

## Parameters

- `col`: The column to remove.

## Discussion

Discussion The column’s cells are autoreleased. This method redraws the receiver. Your code should normally send sizeToCells() after invoking this method to resize the receiver so it fits the reduced cell count.
