JTABLE updating

[Capn_Pipp]

#1 - I'm a newb to java :(
#2 Im having a problem getting getting my JTable to update when the user edits a cell. Im using a abstract model which is basically what the sun tutorial did word for word( i used a abstractmodel so i could make columns uneditable). Also another problem im having is my code to generate stats on row values uses Math Commons library but I have to repeat my code 25 times to do all the rows in the table

public class tables extends JPanel
 {
    public tables() {
        super(new GridLayout(1,0));
 
        JTable table = new JTable(new MyTableModel());
        table.setPreferredScrollableViewportSize(new Dimension(500, 70));
        table.setFillsViewportHeight(true);
        table.getModel().addTableModelListener(table);
        
        //Create the scroll pane and add the table to it.
        JScrollPane scrollPane = new JScrollPane(table);
 
        //Add the scroll pane to this panel.
        add(scrollPane);
        
     // ROW 1 STATS ---------| I repeat this 25x to fill my rows :(
        DescriptiveStatistics stats = new DescriptiveStatistics();
        for (int colx = 1; colx<5; colx++){
        double data[] = {(Double)table.getValueAt(0,colx)};
    	  for( int i = 0; i < data.length; i++) {
              stats.addValue(data[i]);
             
      }} 	
        
    
        double mean = stats.getMean();
        double std = stats.getStandardDeviation();
        double cv = std/mean * 100;
        double setcv = 5.10;
        String accept = "Accepted";
        String unacc = "Unaccepted";
        table.setValueAt(mean,0,5);
        table.setValueAt(std,0,6);
        table.setValueAt(cv,0,7);
        table.setValueAt(setcv,0,8);
        System.out.print(mean);
       
        if (cv <= setcv){
        	table.setValueAt(accept,0,9);
        }
        else{ 
        	table.setValueAt(unacc,0,9);
        }
