Change text size of Textbutton in LibGDX

Question

I am new to Libgdx and I have been searching for 3 hours to find a way to change text size in text button but I couldn't find any method for this. What should I do to do this.

    Table rootTable = new Table();
    rootTable.setFillParent(true);
    rootTable.setDebug(true, true);

    Table menuTable = new Table();
    rootTable.add(menuTable).expand().center().right();

    Skin skin = new Skin(Gdx.files.internal("data/uiskin.json"));

    TextButton singlePlayer = new TextButton("Single Player",skin);
    TextButton multiPlayer = new TextButton("Multi Player", skin);
    TextButton options = new TextButton("Options", skin);
    TextButton exit = new TextButton("Exit", skin);

    int x = Gdx.graphics.getHeight();
    int unit = x / 6;

    float scale = unit / singlePlayer.getHeight();

    float width = singlePlayer.getWidth() * scale;

    menuTable.add( singlePlayer ).size( width,unit).right().row();
    menuTable.add( multiPlayer ).size( width,unit).right().row();
    menuTable.add( options ).size( width,unit).right().row();
    menuTable.add( exit ).size( width,unit).right().row();

Use textButton.getLabel().setFontScale(x, y).
