데이터베이스에서 행을 삭제한 후 JTable이 업데이트되지 않는 이유는 무엇입니까?

delete.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {

        int rowIndex = table.getSelectedRow();

        Object columnIndexValue = table.getModel().getValueAt(rowIndex, 0);

        String columnName = table.getModel().getColumnName(0);

        String query = "delete from world.city" + " where " + columnName + "=" + columnIndexValue;

        try {

            PreparedStatement pre = conn.prepareStatement(query);

            pre.executeUpdate();

            JOptionPane.showMessageDialog(null, "Row Deleted Successfully");
            
            // Notify the table model that the data has changed
            ((TableModel) table.getModel()).fireTableRowsDeleted(rowIndex, rowIndex);

        } catch (Exception e1) {
            JOptionPane.showMessageDialog(null, e1.getMessage());
        }

    }

});
