JTable getColumnName not working with numbered rows

Question

you know when you read through the same code for a day and can't find the problem but someone who has never seen it before can find the problem in a second? i've got that going on right now.
I saw a thread, http://forum.java.sun.com/thread.jspa?forumID=57&threadID=639189 , where rows numbers are neatly added to a JTable by camickr, after I implemented this I can't get my data or ColumnHeaders to line up with the corrent columns. I have three columns, { Integer, Integer, JComboBox } it's kind of an old post but I was just wondering if any one else had run into the problem.
Also when I insert a new row { Integer, Integer, "Combo Option" } it is inserted into the table as { Integer, "Combo Option", Integer }, this isn't a real high priority but any help would be appreciated, thanks.

Answer 1

I tried to shorten this up as much as possible, sorry but it is still kind of big:
//Main class
import java.awt.*;
import java.awt.event.*;
public class TableProblem extends javax.swing.JFrame
     BoreDataJTable table;
     javax.swing.JScrollPane jsp;
     public TableProblem()
          BoreDataDefaultTableModel model = new BoreDataDefaultTableModel( 0, 3 );
          table = new BoreDataJTable( model );
          table.getTableHeader().setReorderingAllowed( false );
          jsp = new javax.swing.JScrollPane( table );
          jsp.setViewportView( table );
          this.setContentPane( jsp );
     public static void main(String args[])
          System.out.println("Starting App");
          TableProblem f = new TableProblem();
          f.setSize(300,100);
          f.show();
//JTable class
import javax.swing.*;
import javax.swing.table.*;
import java.awt.Component;
public class BoreDataJTable extends JTable
     public BoreDataJTable( TableModel tm )
          super( tm );
          setAutoCreateColumnsFromModel( false );
          setAutoscrolls( false );
          addColumn( new TableColumn() );
          getColumnModel().getColumn(0).setCellRenderer( this.getTableHeader().getDefaultRenderer() );
          getColumnModel().getColumn(0).setPreferredWidth( 25 );
          getColumnModel().getColumn(0).setCellEditor( null );
          getColumnModel().getColumn(0).setResizable( false );
          getColumnModel().getColumn(1).sizeWidthToFit();
          getColumnModel().getColumn(2).sizeWidthToFit();
          setPreferredScrollableViewportSize( getPreferredSize() );     
          initGroundColumn( this.getColumnModel().getColumn(3) );
     public boolean isCellEditable(int row, int column)
          if( column < 3 )
               return false;
          else
               return true;
     public Object getValueAt( int row, int col )
          if( col == 0)
               return new Integer( row + 1 );
          else
               DefaultTableModel model = ( ( DefaultTableModel )(
                                 this.getModel() ) );
               return model.getValueAt( row, col - 1 );
     public void initGroundColumn( TableColumn groundColumn )
          JComboBox comboBox = new JComboBox();
          comboBox.addItem( "Select" );
          comboBox.addItem( "Top Soil" );
          comboBox.addItem( "Clay" );
          comboBox.addItem( "Sand" );
          comboBox.addItem( "Gravel" );
          comboBox.addItem( "Pit Run" );
          comboBox.addItem( "Sand Stone" );
          comboBox.addItem( "Bed Rock" );
          groundColumn.setCellEditor(new DefaultCellEditor(comboBox));
          DefaultTableCellRenderer renderer = new DefaultTableCellRenderer();
          renderer.setToolTipText("Select Ground Type");
          groundColumn.setCellRenderer(renderer);
//DefaultTableModel class
import javax.swing.table.*;
import javax.swing.*;
public class BoreDataDefaultTableModel extends DefaultTableModel
     private final Object[] emptyRow = { new Integer(0), new Integer(0), "Select" };
     private final String[] colNames = { null, "Depth (cm)", "Angel (%)", "Ground" };
     int cols;
     int rows;
     public BoreDataDefaultTableModel( int rows, int cols )
          super( rows, cols );
          this.rows = rows;
          this.cols = cols;
          addRow( emptyRow );
     public String getColumnName( int col )
          return colNames[col];
}The problem is that when the JComboBox is changed, it changes the value in the "Depth" to the the JComboBox's value, also it doesn't correctly display the ColumnHeader for the JComboBox's column
