How to put ComboBoxTableCell in a TableView?

Question

I'm trying to put a ComboBox in a table cell, but I can't. the code is the next:

private void cargaTablaDesglose() {
    TableColumn<Map, String> column1 = new TableColumn<>(Desglose1);
    TableColumn<Map, String> column2 = new TableColumn<>(Desglose2);
    TableColumn<Map, String> column3 = new TableColumn<>(Desglose3);

    column1.setCellValueFactory(new MapValueFactory(Desglose1));
    column1.setMaxWidth(0);
    column2.setCellValueFactory(new ComboBoxTableCell.forTableColumn(null));
    column2.setPrefWidth(150);
    column3.setCellValueFactory(new MapValueFactory(Desglose3));
    column3.setPrefWidth(250);

    if (CUOD.modifyData()) {
        column2.setOnEditCommit((TableColumn.CellEditEvent<Map, String> t) -> {
            actualizaObra(t.getRowValue(), t.getNewValue());
        });
            }

    tablaDesglose.getItems().clear();
    tablaDesglose.setEditable(true);
    tablaDesglose.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
    tablaDesglose.getSelectionModel().setCellSelectionEnabled(false);
    tablaDesglose.getColumns().clear();
    tablaDesglose.getColumns().addAll(column1, column2, column3);

    Callback<TableColumn<Map, String>, TableCell<Map, String>> cellFactoryMap
            = CUCF.getFactoryMap();
    column1.setCellFactory(cellFactoryMap);
    column2.setCellFactory(cellFactoryMap);
    column3.setCellFactory(cellFactoryMap);
}

It says that can't found forTableColumn method of ComboBoxTableCell

The part of the problem is that you're trying to set cell factory into cell value factory field of TableColumn. Try this instead:

ObservableList<String> cbValues = FXCollections.observableArrayList("1", "2", "3");

TableColumn<Map, String> column2 = new TableColumn<>(Desglose2);
column2.setCellFactory(ComboBoxTableCell.forTableColumn(new DefaultStringConverter(), cbValues));
