java swing定制表格单元格？

Question

在java Swing表中，如何将一个单元格拆分为两个，一个是TextField，另一个是复选框。我做了一些代码，但不起作用。感谢

public class CustomTableCellRenderer extends DefaultTableCellRenderer {
        public Component getTableCellRendererComponent(JTable table, Object obj, boolean isSelected, boolean hasFocus, int row, int column) {
            Component cell = super.getTableCellRendererComponent(table, obj, isSelected, hasFocus, row, column);
            JTextField fld = new JTextField();
            JCheckBox chx = new JCheckBox();
            cell.add(fld);  // Doesn't work
            cell.add(chx);  // Doesn't work

            return cell;
        }
    }

1）在这种情况下，您必须为LayoutManager定义，因为JLabel/JComponent（默认情况下返回TableCellRenderer）不会implemented any LayoutManager

2）将JPanel nested another JComponents（JPanel默认为FlowLayout）放入单元格

3）大多数可以将JTextField置于一个列，将Boolean值（返回JCheckBox）放到另一列
