Swift 4.2

Create an extension and add a method which preserves selection.

extension NSTableView {

    func reloadDataKeepingSelection() {
        let selectedRowIndexes = self.selectedRowIndexes
        self.reloadData()
        self.selectRowIndexes(selectedRowIndexes, byExtendingSelection: false)
    }
}

Do this in case you use the traditional way of populating table views (not NSArrayController).
