String[] columnName = new String[]{"1", "2", "3"};
DefaultTableModel tableModel = new DefaultTableModel(data, columnName);
JTable table = new JTable(tableModel) {

public TableCellRenderer getCellRenderer(int row, int column) {
TableCellRenderer renderer = super.getCellRenderer(row, column);
if (renderer instanceof JLabel) {
