JavaSwing:如何添加一个显示日期的CyrReReDelver?

我有一张桌子:

public class AppointmentTableModel extends AbstractTableModel {
    private int columns;
    private int rows;
    ArrayList<Appointment> appointments;...

所以表的每一行都包含一个约会。

public class Appointment {

    private Date date;
    private Sample sample;
    private String comment;
    private ArrayList<Action> history;

    public Appointment(Date date, Sample sample, String comment) {
        this.date = date;
        this.sample = sample;
        this.comment = comment;
        this.history = new ArrayList<Action>();
    }

    public Object getByColumn(int columnIndex) {
        switch (columnIndex) {
        case 0: return date;//Date: dd:mm:yyyy

        case 1: return date;//Time mm:hh

        case 2: return sample;//sample.getID() int (sampleID)

        case 3: return sample;//sample.getNumber string (telephone number)

        case 4: return sample;//sample.getName string (name of the person)

        case 5: return history;//newst element in history as a string

        case 6: return comment;//comment as string


        }
        return null;

我在评论中补充了这句话的意思。我如何创建cellrenderer来显示它。

   table.getColumnModel().getColumn(1).setCellRenderer(new DateRenderer());

我还想添加整行,以便在日期晚于当前日期时用红色绘制。 然后是另一列,其中包含一个jbutton,以打开另一个屏幕,并将相应的约会作为参数。
