Why TableView / TableColumn is not editable?

From the following FXML:

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.image.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.text.*?>

<VBox spacing="10" xmlns:fx="http://javafx.com/fxml">
   <Label     fx:id="_lru"     styleClass="wizard-title-centered" />
   <Label     fx:id="_prompt"  styleClass="wizard-label" />
   <TableView fx:id="_tableVw" maxWidth="560" prefHeight="200" editable="true">
     <columns>
       <TableColumn fx:id="_name"            prefWidth="220" editable="false" />
       <TableColumn fx:id="_partNum"         prefWidth= "80" editable="false" />
       <TableColumn fx:id="_serialNum"       prefWidth= "84" editable="true"  />
       <TableColumn fx:id="_calibrationDate" prefWidth="120" editable="true"  />
       <TableColumn fx:id="_available"       prefWidth= "40" editable="false" />
     </columns>
   </TableView>
   <Text fx:id="_note" wrappingWidth="550" styleClass="wizard-label" />
</VBox>

Associated to the following Java class:

public class Page extends AbstractPage<Data> implements Initializable {

   @FXML private Label                          _lru;
   @FXML private Label                          _prompt;
   @FXML private TableView<Record>              _tableVw;
   @FXML private TableColumn<Record, String>    _name;
   @FXML private TableColumn<Record, String>    _partNum;
   @FXML private TableColumn<Record, String>    _serialNum;
   @FXML private TableColumn<Record, LocalDate> _calibrationDate;
   @FXML private TableColumn<Record, Boolean>   _available;
   @FXML private Text                           _note;

   @Override
   public void initialize( URL location, ResourceBundle resources ) {
      _lru            .setText( _worker.getData()._tpsSoftName );
      _prompt         .setText( I18n.get("EXTERNAL_RC_PROMPT"   ));
      _name           .setText( I18n.get("EXTERNAL_RC_NAME"     ));
      _partNum        .setText( I18n.get("EXTERNAL_RC_PARTNUM"  ));
      _serialNum      .setText( I18n.get("EXTERNAL_RC_SERIALNUM"));
      _calibrationDate.setText( I18n.get("EXTERNAL_RC_CALIB"    ));
      _available      .setText( I18n.get("EXTERNAL_RC_AVAILABLE"));
      _note           .setText( I18n.get("EXTERNAL_RC_NOTE"     ));
      _name           .setCellValueFactory(new PropertyValueFactory<Record, String>   ("name"));
      _partNum        .setCellValueFactory(new PropertyValueFactory<Record, String>   ("partNum"));
      _serialNum      .setCellValueFactory(new PropertyValueFactory<Record, String>   ("serialNum"));
      _calibrationDate.setCellValueFactory(new PropertyValueFactory<Record, LocalDate>("calibrationDate"));
      _available      .setCellValueFactory(new PropertyValueFactory<Record, Boolean>  ("available"));
      _calibrationDate.setCellFactory(
         new Callback<TableColumn<Record,LocalDate>, TableCell<Record,LocalDate>>() {
         @Override public TableCell<Record,LocalDate> call( TableColumn<Record,LocalDate> c ) {
             return new DatePickerCell<>(); }});
      _available.setCellFactory(
         new Callback<TableColumn<Record,Boolean>, TableCell<Record,Boolean>>() {
         @Override public TableCell<Record,Boolean> call( TableColumn<Record,Boolean> c ) {
             return new CheckBoxTableCell<>(); }});
   }

   @Override
   public void processDone( boolean successfully ) {
      _tableVw.getItems().setAll( _worker.getData()._resources);
   }
}

Double-clicking serialNum columns doesn't activate the underlying TextField when "calibration date" column is editable. Why?

This is because the default cell factory doesn't provide an editor as specified in the documentation of javafx.scene.control.cell.TextFieldTableCell.

By default, the TextFieldTableCell is rendered as a Label when not being edited, and as a TextField when in editing mode. The TextField will, by default, stretch to fill the entire table cell.

Adding the following code do the job.

_serialNum.setCellFactory( TextFieldTableCell.<Record>forTableColumn());
