Answer 1

Your class MyTableModel implements TableModel, but it has no event handling mechanism to connect the model to the view. Instead extend AbstractTableModel, as shown here and here. AbstractTableModel provides the fireTable* methods needed for this.

public void setValueAt(Object value, int row, int col) {
    data[row][col] = value;
    fireTableCellUpdated(row, col);
}
