libgdx: Adding Table to Stage causes Actors that aren't children of the Table to not render, despite not having overlapping coordinates - libgdx

Question

So, I have a Game Screen that I have set to 800x480, and at the top of that screen I'm trying to create a Table that contains some information. I've set the table bounds to x = 0, y = 380, width = 800, height = 100, and when the screen renders, the table shows up at the top of the screen just like I want. However, below that table, I want to render additional Actors that I've added to my stage. Problem is, they aren't rendering. If I comment out the line where I add the table to the stage, everything renders just fine - its only when I add the table that the issue occurs, even though the non-Table Actors don't overlap screen coordinates with the Table. For the purpose of this question, I cut out all of the Actors other than the one called "Field", which is a game board with coordinates of x=0, y=0, width=500, height=300.
Why is the inclusion of the Table obfuscating the rendering of my other Actors?
Here's my code (first GameScreen, then Field):
public GameScreen(MyGame game) {
// TODO Auto-generated constructor stub
this.game = game;
log = "Starting game";
plyscore = 0;
oppscore = 0;
stage = new Stage(new StretchViewport(800,480));
gameskin = new Skin(Gdx.files.internal("uiskin.json"));
gametable = new Table();
background = new TextureRegionDrawable(new TextureRegion(AssetLoader.background));
field = new Field();
score = new Label(plyscore+" - "+oppscore, gameskin);
logarea = new TextArea(log, gameskin);
logarea.setPrefRows(3);
logscroll = new ScrollPane(logarea, gameskin);
logscroll.setForceScroll(false, true);
logscroll.setFlickScroll(false);
gametable.setBounds(0, 380, 800, 100);
gametable.add(score).width(390);
gametable.add(logscroll).width(390).row();
stage.addActor(gametable);
stage.addActor(field);
}
#Override
public void render(float delta) {
Gdx.gl.glClearColor(0.0f, 0.5f, 0.2f, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
stage.draw();
}
public class Field extends Actor {
public Field() {
setBounds(getX(), getY(), AssetLoader.field.getRegionWidth(),
AssetLoader.field.getRegionHeight());
}
#Override
public void draw(Batch batch, float alpha){
batch.draw(AssetLoader.field,this.getX(),getY());
}
}
