LibGDX How to put the game in the table? *** FIXED ***

问题

I have a game screen in which I want to implement both the game itself and the control buttons. I divided this screen into two parts using TABLE. The control buttons and the game are implemented in different classes. Everything works correctly, except for displaying the game.

How to make the game fit in the top window?

Game Screen code

public class GameScreen implements Screen {
    private Main parent;
    private Stage stage;
    public static SnakeControl snakeControl;
    private SpriteBatch batch;
    private GameControl game;

    public GameScreen(Main main) {
        parent = main;

        stage = new Stage(new ScreenViewport());
        Gdx.input.setInputProcessor(stage);
        snakeControl = new SnakeControl();

        GameAssets.instance().loadAssets();
        batch = new SpriteBatch();
        game = new GameControl();
    }

    @Override
    public void show() {
        Table table = new Table();
        table.setFillParent(true);
        table.setDebug(true);

        table.row();
        table.add(game).expand().pad(10f, 5f, 10f, 5f);
        table.row();
        table.add(snakeControl.get_tSnakeControl()).fillX().height(GameInfo.SCREEN_HEIGHT/3.5f).pad(0f, 5f, 10f, 5f);

        stage.addActor(table);
    }

    @Override
    public void render(float delta) {
        game.update(Gdx.graphics.getDeltaTime());
        clearScreen();
        batch.begin();
        game.render(batch);
        stage.act(Gdx.graphics.getDeltaTime());
        stage.draw();
        batch.end();
    }

    private void clearScreen() {
        Gdx.gl.glClearColor(0f, 0f, 0f, 1f);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
    }

    @Override
    public void resize(int width, int height) {
        stage.getViewport().update(width, height, true);
    }

    @Override
    public void pause() {

    }

    @Override
    public void resume() {

    }

    @Override
    public void hide() {

    }

    @Override
    public void dispose() {
        stage.dispose();
        batch.dispose();
        GameAssets.instance().dispose();
    }

The Game code

public class GameControl extends Actor {

    private Board board;
    private Snake snake;
    private float timeState;
    private BitmapFont font;

    private GameObject food;
    private boolean isGameOver;

    public GameControl() {
        TextureAtlas atlas = GameAssets.instance().get(GameAssets.SNAKE_PACK);
        font = GameAssets.instance().get(GameAssets.PIXEL_FONT);
        snake = new Snake(atlas);
        board = new Board(snake, GameInfo.SCREEN_WIDTH, GameInfo.SCREEN_HEIGHT);
        food = board.generateFood();
        init();
    }

    private void init() {
        GameSoundsPlayer.init();
        GameSoundsPlayer.playMusic(GameAssets.MEMO_SOUND, false);
    }

    public void update(float delta) {
        if (snake.hasLive()) {
            timeState += delta;
            snake.handleEvents();
            if (timeState >= .09f) {
                snake.moveBody();
                timeState = 0;
            }
            if (snake.isCrash()) {
                snake.reset();
                snake.popLife();
                GameSoundsPlayer.playSound(GameAssets.CRASH_SOUND, false);
            }
            if (snake.isFoodTouch(food)) {
                GameSoundsPlayer.playSound(GameAssets.EAT_FOOD_SOUND, false);
                Scorer.score();
                snake.grow();
                food = board.generateFood();
            }
        } else {
            gameOver();
            if (Gdx.input.isKeyJustPressed(Input.Keys.ANY_KEY)) start();
        }
    }

    private void gameOver() {
        isGameOver = true;
        GameSoundsPlayer.stopMusic(GameAssets.MEMO_SOUND);
        GameSoundsPlayer.playMusic(GameAssets.GAME_OVER_SOUND, false);
    }

    private void start() {
        GameSoundsPlayer.playMusic(GameAssets.MEMO_SOUND, false);
        GameSoundsPlayer.stopMusic(GameAssets.GAME_OVER_SOUND);

        isGameOver = false;
        snake.reset();
        snake.restoreHealth();
        food = board.generateFood();
        Scorer.reset();
    }

    public void render(SpriteBatch batch) {
        board.render(batch);
        food.draw(batch);
        snake.render(batch);

        if (isGameOver) {
            font.draw(batch, "GAME OVER", (GameInfo.SCREEN_WIDTH - 100) / 2, (GameInfo.SCREEN_HEIGHT + 100) / 2);
            font.draw(batch, "Press any key to continue", (GameInfo.SCREEN_WIDTH - 250) / 2, (GameInfo.SCREEN_HEIGHT + 50) / 2);
        }

        font.draw(batch, "Player: ", GameInfo.SCALE * 4, GameInfo.SCREEN_HEIGHT - 10);
        font.draw(batch, "Score: " + Scorer.getScore(), GameInfo.SCALE / 2, GameInfo.SCREEN_HEIGHT - 10);
        font.draw(batch, "Size: " + snake.getBody().size(), GameInfo.SCALE / 2, GameInfo.SCREEN_HEIGHT - 40);
    }
}

I used Viewport for this!!!

@Override
    public void render(float delta) {

        clearScreen();
        Gdx.gl.glViewport(0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight()/3);
        stage.act(Gdx.graphics.getDeltaTime());
        stage.draw();

        Gdx.gl.glViewport(0, Gdx.graphics.getHeight()/3, Gdx.graphics.getWidth(), (Gdx.graphics.getHeight() - Gdx.graphics.getHeight()/3));
        game.update(Gdx.graphics.getDeltaTime());
        batch.begin();
        game.render(batch);
        batch.end();
    }
