In addition to @jeberle 's answer, I need to note something more.

• The key to keep the text-field and image-view is adding them as subviews of the NSTableCellView.

• Set NSTableView.rowSizeStyle to a proper value (non-Custom which is default value) to make the table-view layout them automatically. Otherwise, you have to layout them completely yourself.

• Do not touch frame and autoresizing stuffs if you want to use predefined NSTableViewRowSizeStyle value. Otherwise, the layout might be broken.

• You can adjust row-height by providing private func outlineView(outlineView: NSOutlineView, heightOfRowByItem item: AnyObject) -> CGFloat delegate method. Setting NSTableView.rowHeight is not a good idea because it needs NSTableView.rowSizeStyle set to Custom which will turn off cell text/image layout management provided by default.

• You can reuse row/cell views by settings NSView.identifier property. (example)
