LibGDX表单元格大小

Question

我有两个TextureRegionDrawable，每个按钮一个，然后将它们添加到表中，然后添加到舞台中。问题是我尝试更改表格的高度和宽度，但是按钮变小了。图像有问题吗？

    TextureAtlas ta = new TextureAtlas("Agorafunfa.txt");
    final TextureAtlas.AtlasRegion as = ta.findRegion("comeca");
    final TextureAtlas.AtlasRegion as2 = ta.findRegion("comecaversao2");
    myTexRegionDrawable2 = new TextureRegionDrawable(as2);
    myTexRegionDrawable = new TextureRegionDrawable(as);
    myTexRegionDrawable.setMinWidth(260);
    myTexRegionDrawable.setMinHeight(300);
    myTexRegionDrawable2.setMinHeight(300);
    myTexRegionDrawable2.setMinWidth(260);
    b = new ImageButton(myTexRegionDrawable);
    op = new ImageButton(myTexRegionDrawable2);
    b.addListener(new ClickListener() {
        @Override
        public void clicked(InputEvent event, float x, float y) {
            gdxGame.setScreen(new Janela2(gdxGame));
        }
    });
    t = new Table();
    t.row().padRight(100);
    t.add(b);
    t.row().padRight(100);
    t.debug();
    t.add(op);
    t.setFillParent(true);
    stage.addActor(t);
    Gdx.input.setInputProcessor(stage);
}
