    Help me with alignment. GridBagLayout
    Did you read the documentation? How to Use GridBagLayout (The Java™ Tutorials > Creating a GUI With JFC/Swing > Laying Out Components Within a Container)

    Anyway, here you have a small code which uses GridBagLayout ... hope it helps.

    private void buildGui() {
    		Container contentPane = this.getContentPane();
     
    		contentPane.setLayout(new GridBagLayout());
     
    		contentPane.add(ngFiltersPanel, new GridBagConstraints(0, 0, 1, 1, 1, 0, GridBagConstraints.CENTER,
    				GridBagConstraints.HORIZONTAL, new Insets(5, 5, 5, 5), 0, 0));
    		contentPane.add(table, new GridBagConstraints(0, 1, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.BOTH,
    				new Insets(0, 5, 5, 5), 0, 0));
    		contentPane.add(buttonVolver, new GridBagConstraints(0, 2, 1, 1, 1, 0, GridBagConstraints.EAST, GridBagConstraints.NONE,
    				new Insets(0, 5, 5, 5), 0, 0));
    	}
