Libgdx Table too small, does not fill viewport

I'm trying to use a Table to create a menu with lined-up Buttons and Labels. I'm using the latest nightly builds of libgdx, which changed the Table API (amongst other things).

Here's the code in my Screen constructor:

this.mStage = new Stage();
this.mTable = new Table();
this.mTable.setFillParent(true);
this.mTable.debugTable();
this.mStage.addActor(this.mTable);

// now I add some stuff to the table
// ...

My resize function looks like this:

this.mStage.setViewport(width, height, true);
this.mTable.setFillParent(true);
this.mTable.invalidate();

My render function has the following:

System.out.println("Table size is " + 
    this.mTable.getWidth() + " by " + 
    this.mTable.getHeight());
this.mStage.draw();
Table.drawDebug();

Although my console shows the correct size:

Table size is 480.0 by 640.0

the Table size is shrink-wrapped around its children, and does not extend to the correct size of 480x640.

Any ideas?

To add to the above answers, it may be helpful to know that you can make these setting defaults for the table like so:

this.mTable.defaults().expandX().fillX();

The settings will apply uniformly to all rows and cells.

Your incorrect version of adding widget to the table can be easily corrected by expanding a cell first using .expandX() method and then by filling that cell with a widget by calling fillX(). so your initial code:

this.mTable.row();
this.mTable.add(button).fillX();

should be corrected to the following version:

this.mTable.row();
this.mTable.add(button).expandX().fillX();

these 2 lines can be shorten to one:

this.mTable.add(button).expandX().fillX().row();

Answering my own question for the benefit of others. The way I was adding widgets to the table was incorrect:

this.mTable.row();
this.mTable.add(button).fillX();

I needed to call the fillX() method of the row():

this.mTable.row().fillX();
this.mTable.add(button);

Hope this helps someone.
