In your onCreate() method you need to add a listener to the button and in that listener you can retrieve the view (table layout) and modify its properties. To find the button and the view you're changing you'll need to specify IDs for them in the XML (assuming you're inflating it from XML). Try something like this (untested) code:

Button button = (Button) findViewById(R.id.mybutton);
button.setOnClickListener(new OnClickListener()
{
    @Override
    public void onClick(final View view)
    {
            TableLayout tableLayout = (TableLayout) findViewById(R.id.mytablelayout);
            tableLayout.setBackgroundResource(R.drawable.mybackgroundimage);
    }
});
