JavaFX TableView editable(true) don't work

I have this code:

public static void main(String[] ar){ launch(ar); }

@Override
public void start(Stage primaryStage){

    TableView<Foo> tableView = new TableView<>();
    tableView.setColumnResizePolicy(TableView.UNCONSTRAINED_RESIZE_POLICY);
    tableView.setPlaceholder(new Label("No data"));
    tableView.setEditable(true);

    TableColumn<Foo, String> colText = new TableColumn<>("Text");
    colText.setCellValueFactory(new PropertyValueFactory<>("text"));

    tableView.getColumns().add(colText);

    List<Foo> listFoo = new ArrayList<>(Arrays.asList(new Foo("1"), new Foo("2"), new Foo("3")));

    tableView.setItems(FXCollections.observableArrayList(listFoo));

    primaryStage.setScene(new Scene(tableView));
    primaryStage.show();

}

public class Foo{

    private String text;

    public Foo(String txt){ text = txt; }

    public String getText(){ return text; }

    public void setText(String text){ this.text = text; }

}

I try to make the cells of table editable: tableView.setEditable(true);, but it don't work.

How can I make cells of table editable or to have posibility to copy the value from cell into clipboard.

For a TableCell to be editable, 3 conditions need to be fulfilled:

  1. The containing TableView is editable
  2. The containing TableColumn is editable
  3. The cell itself is editable

In your case the 3rd condition is not fulfilled, since the cells created by the default cellFactory are not editable. You need to assign a cellFactory that allows for editing. Furthermore note that unless the cellValueFactory returns an object implementing WritableValue, you also need to use the onEditCommit handler to store the data in the item:

colText.setCellFactory(TextFieldTableCell.forTableColumn());
colText.setOnEditCommit(evt -> evt.getRowValue().setText(evt.getNewValue()));
