Trying to hide columns while using Default table Model - JTable

I have extended JTable as follows...

public class MyTable extends JTable
{
    public MyTable()
    {
        super();
    }
    public MyTable(java.lang.String resourceTag, javax.swing.table.TableModel tableModel)
    {
        super(resourceTag, tableModel);
    }

    public void createDefaultColumnsFromModel()
    {       super.createDefaultColumnsFromModel();
        TableColumnModel model = getColumnModel();
columnModel.getColumn(3);
            this.removeColumn(column);
        }
        model.removeColumn(model.getColumn(3));
       
    }
}

in my Dialog I am implementing...

protected MyTable m_tblSetMetric = null;

m_tblmdlSetMetric     =  new MDefaultTableModel("setMetricLis", dataOut);
m_tblSetMetric           =   new MyTable("setMetricLis", m_tblmdlSetMetric);
m_tblSetMetric.createDefaultColumnsFromModel();
MTablePane tp           =   new MTablePane(12, true, null, (MTable)m_tblSetMetric, m_tblmdlSetMetric);
......

I am not getting any exception but the dialog doesn't show me the column names that I am trying to pull from properties file. If I comment out

model.removeColumn(model.getColumn(3));


line then it shows all the columns...Am I missing somethign or doing wrong...
Appreciate any help...
thanks
