How to get NSTableView to use a custom cell view mixed with preset cell views?

I have a NSTableView configured in Interface Builder which uses several default cell views. However the first column's cell view needs to be created from a custom class. How do I implement NSTableViewDataSource method tableView.viewForTableColumn() so that it creates the default cell views for the remaining columns?

Here's my method so far:

func tableView(tableView:NSTableView, viewForTableColumn tableColumn:NSTableColumn?, row:Int) -> NSView?
{
    /* Create custom cell view for first column. */
    if (tableColumn?.identifier == "nameColumn")
    {
        let view = tableView.makeViewWithIdentifier("nameCellView", owner: nil) as! NameTableCellView;
        return view;
    }

    /* Return default cell views (defined in IB) for the rest. */
    return tableView.viewAtColumn(??, row: row, makeIfNecessary: true); // How to get column index??
}

How do I get the right column index for tableView.viewAtColumn()? tableView.columnForView() or tableView.columnWithIdentifier() are obviously not any option in this case.

I'd try just giving the default cell your own identifier in Interface Builder...

...then just use that in conjunction with makeViewWithIdentifier::

func tableView(tableView: NSTableView,
    viewForTableColumn
    tableColumn: NSTableColumn?, row: Int) -> NSView? {

        var viewIdentifier = "StandardTableCellView"

        if let column = tableColumn {

            switch column.identifier {

            case "nameColumn":
                viewIdentifier = "nameCellView"

            default: break

            }
        }

        return tableView.makeViewWithIdentifier(viewIdentifier, owner: self) as? NSView
}
