Re-implementing DefaultTableModel.addRow()

Question

re-implemented addRow() to pass in type TableRow(class I implemented) which is similar to the the addRow() in the default implementation but doesn't require the calling class to know the column order of the data. So my table model just stores the TableRows in a Vector. I was working on the assumption that if I called fireTableChanged() in my addRow() method, that getValueAt() will get called to refresh the JTable. Thedoesn't work! Does anyone know what calls need to be made to get the table to refresh when a new row is added, or any docs that explains this?
Thanks.

this is how i do it. I've added this function to TableSorter.java from sun's demos. Hope this helps.
public void addRow(JTable table, Object[] newRowData) {
int cc = getColumnCount();
int rc = getRowCount();
Object[][] curr= new Object[rc+1][cc];
for (int c=0; c < cc; c++){
          for (int r=0; r < rc; r++){
               curr[r][c] = data[r][c];     
          try{
          curr[data.length][c] = newRowData[c];
     }catch(Exception e){
     curr[data.length][c] = "";
this.setRowData(curr); //method I created in MyTableModel class
this.reallocateIndexes(); //see below
this.updateTable(); //see below
table.repaint();
public final void updateTable(){
     super.tableChanged(new TableModelEvent(this));
public void reallocateIndexes() {
     int rowCount = getRowCount();
               indexes = new int[rowCount];
               for (int row = 0; row < rowCount; row++) {
     indexes[row] = row;
               int colCount = getColumnCount();
               colindexes = new int[colCount];
               for (int col = 0; col < colCount; col++) {
     colindexes[col] = col;
     }
