How to get TableCell node of row selected

I have the following code that I use whenever a user selects a row. Is there any way you can grab the first or the selected cell from the selected row? I need the selected cell because I want the pass that node to the ControlsFX POPOVER.show() method. I need the popover box to appear right over the selected row in the tableview. 

tableView.setRowFactory(tv -> {
    TableRow<ObservableList> row = new TableRow<>();
    row.setOnMouseClicked(event -> {
        if (event.getClickCount() == 2 && (!row.isEmpty())) {
            popover.show(cellNodeHere<-);
        }
    });

    return row;
});

The solution for me was to use the row as the Node and also turn the arrow location

popup.setArrowLocation(PopOver.ArrowLocation.BOTTOM_CENTER);

This way, the popup shows up right over the TableRow

In your last question just change the row factory to this. You can use getCellData.

Label label = new Label("click a row");
tableView.setRowFactory(tv -> {
   TableRow<ObservableList> row = new TableRow<>();    
   row.setOnMouseClicked(event -> {
       if (event.getClickCount() == 2 && (!row.isEmpty())) {
           //if you want the y coord of the row in the scene
           double y = ((TableRow)event.getSource()).getLocalToSceneTransform().getTy();
           int idx = tableView.getSelectionModel().getSelectedIndex();
           label.setText(idx 
               + " <-tbl row, idx in items-> "
               + items.indexOf(tableView.getSelectionModel().getSelectedItem())
               + ", first cell-> "
               + ((TableColumn)tableView.getColumns().get(0)).getCellData(idx));
       }
   });
   return row;
});
