JTable in JPanel cut off

Question

I'm trying to put a JTable with several elements in a JPanel and it is getting cut off. I have tried extending the gridbagconstraints with ipady but no luck.
public class PumpMonitor extends JPanel
JTable Table1;
PumpMonitor()
Table1Model dm = new Table1Model();
Table1 = new JTable( dm ) ;
GridBagLayout gridBagLayout3 = new GridBagLayout();
gridBagLayout3.rowHeights[0] = 300;
Dimension size = new Dimension(300,400);
this.setMinimumSize(size);
this.setVisible(true);
this.setPreferredSize(size);
this.setMaximumSize(size);
this.setLayout(gridBagLayout3);
Table1.setBackground(Color.white);
Table1.setEnabled(false);
GridBagConstraints c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 1;
c.ipady = 10;
c.gridwidth = 100;
c.anchor = GridBagConstraints.NORTHWEST;
gridBagLayout3.setConstraints(hel,c);
this.add(hel);
this.add(Table1, new GridBagConstraints(0, 0, 1, 1, 1.0, 1.0
,GridBagConstraints.CENTER, GridBagConstraints.BOTH, new Insets(0, 0, 0, 0), 74, 500));
class Table1Model extends AbstractTableModel
Object[][] Table1Data =
{"Address",new String()},
{"Serial #" ,new String()},
{"SW Revision" ,new String()},
{"ETM" ,new String()},
{"T1",new String()},
{"T2" ,new String()},
{"TC/Vac Gauge" ,new String()},
{"Aux TC" ,new String()},
{"Motor Speed",new String()},
{"Set Values" ,new String()},
{"Heater Pwr T1" ,new String()},
{"Heater Pwr T2" ,new String()},
public void setValueAt (Object value, int row, int col)
     Table1Data[row][col] = value;
     public int getColumnCount()
return Table1Data[0].length;
public int getRowCount()
return Table1Data.length;
/* public String getColumnName(int col)
return (String)headers[col];
public Object getValueAt(int row,int col)
return Table1Data[row][col];
};

Thanks Denis.
I did this:
JScrollPane scroll = new JScrollPane(Table1);
this.add(scroll, new GridBagConstraints(0, 0, 1, 3, 1.0, 1.0
,GridBagConstraints.NORTHWEST, GridBagConstraints.BOTH, new Insets(0, 0, 0, 0), 74, 500));
That works but I want to see the whole table at once. Is there something I can do to do that?
