In a table with cell selection, the very first navigation into the table (by key-down) results in selecting the last cell of the first row when it should be the first.

To reproduce, run the example
- note that the table is focused (without any default focus in the content, neither row nor cell - bug or feature?)
- press key-down to move into the table
- expected: first cell of first row selected
- actual: last cell of first row selected

The workaround is to focus the first cell programatically - initially and probably after any change to the data that results in focusModel having nothing focused (not tested, though)

The example:

public class TableInitialCellSelection extends Application {

    private Parent createContent() {
        ObservableList<Locale> data = FXCollections.observableArrayList(
                Arrays.stream(Locale.getAvailableLocales(), 10, 20).collect(Collectors.toList()));
        TableView<Locale> table = new TableView<>(data);
        table.getColumns().addAll(createTableColumn("displayLanguage"), createTableColumn("displayCountry"));
        table.getSelectionModel().setCellSelectionEnabled(true);
        return new BorderPane(table);
    }

    private <T> TableColumn<T, String> createTableColumn(String property) {
        TableColumn<T, String> column = new TableColumn<>(property);
        column.setCellValueFactory(new PropertyValueFactory<>(property));
        return column;
    }

    @Override
    public void start(Stage stage) throws Exception {
        stage.setScene(new Scene(createContent()));
        //stage.setTitle(FXUtils.version());
        stage.show();
    }

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

    @SuppressWarnings("unused")
    private static final Logger LOG = Logger
            .getLogger(TableInitialCellSelection.class.getName());
