JTable column names with custom model

Question

I'm having problems with column names in a JTable which uses a custom model. For some reason, the colums are being shown as A, B, C etc. The data, however, displays fine.
This is the code which constructs the table.
MyTableModel tableModel = new MyTableModel(myArrayList);
  myTable = new JTable(tableModel);
  myTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
  myTable.setFillsViewportHeight(true);This is the class, MyTableModel
class MyTableModel extends AbstractTableModel {
        private ArrayList<Account> data;
        private String[] colNames = {"", "Name","Type","Group","Created","Modified"};
        public MyTableModel(ArrayList<Account> data) {
            this.data = data;
        public int getRowCount() {
            return data.size();
        public int getColumnCount() {
            return 6;
        public Object getValueAt(int row, int col) {
            Account account = (Account)data.get(row);
            switch(col) {
                case 0:
                    return account.getIcon();
                case 1:
                    return account.getName();
                case 2:
                    return account.getType();
                case 3:
                    return account.getGroup();
                case 4:
                    return account.getDateCreated();
                case 5:
                    return account.getDateModified();
                default:
                    return "";
        public String getColumName(int index) {
         System.out.println("N:"+colNames[index]);
            return colNames[index];
    }When the table is displayed, nothing's displayed to the console, but I'd have thought getColumnName would print the current column name. Am I missing something obvious?
