The sub implementations of Tree- and TableCell shipped by JavaFX do not respect the row editability (inside startEdit()).
This issue persists also in the standard Tree- and TableCell. (see JDK-8252238)

Affected classes:
- ComboBoxTableCell
- ComboBoxTreeTableCell
- ChoiceBoxTableCell
- ChoiceBoxTreeTableCell
- TextFieldTableCell
- TextFieldTreeTableCell

There are also 2 special cases: CheckBoxTableCell and CheckBoxTreeTableCell.
In this cells the corresponding CheckBox should consider the row editability when the disablement is calculated.
It is also recommended to do a null check before using the row editability.
There is a follow-up for this here: JDK-8270042

--- EXAMPLE ---

---------- BEGIN SOURCE ----------
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableRow;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.TextFieldTableCell;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;

public class TableViewBug extends Application {
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) {
        TableView<Object> table = new TableView<>();
        table.setEditable(true);
        table.getItems().add(new Object());
        TableColumn<Object, Boolean> column = new TableColumn<>("Select Me");
        column.setCellFactory(p -> new TextFieldTableCell<>());
        table.getColumns().add(column);
        table.setRowFactory(p -> {
            TableRow<Object> row = new TableRow<>();
            row.setEditable(false);
            return row;
        });
        Pane root = new Pane();
        root.getChildren().add(table);
        Scene scene = new Scene(root);
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
TextFieldTableCell should not be editable
ACTUAL -
TextFieldTableCell is editable
