Bingo ! Thanks to Willeke I rewrote my code as follows :

var donnees: DataFrame = DataFrame()    // Some table-like data with unspecified number of columns

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    initData()      // get the actual data
    self.setTableColumns() // and prepare the columns accordingly
}
    func setTableColumns() {
    // In Interface Builder I've prepared a cell view in the 0-th tableColumn and set the identifier of this NSTableColumn to "ModelCellView"
        let myCellViewNib = dataTable.registeredNibsByIdentifier!["ModelCellView"]   // I save the cellView's Nib
    //      Make the ad-hoc number of columns
        if donnees.nbCol > 0 {
            for k in 0.. Int {
    return self.donnees.nbRow
}  
extension MyViewController : NSTableViewDelegate {
func tableView(tableView: NSTableView, viewForTableColumn tableColumn: NSTableColumn?, row: Int) -> NSView? {
    let columnID = tableColumn!.identifier
    let cellView = tableView.makeViewWithIdentifier(columnID, owner: self) as! NSTableCellView
    cellView.textField?.stringValue = "theActualCellData"
    return cellView
}  

And it works perfectly as intended. Again, thanks to Willeke.
