Java 在JTable中显示哈希表数据？

我有一个哈希表

hashtable c = new Hashtable();

Employee emp = new Employee("E1001","Sky");
c.put("E1001",emp);

然后我有一个JTable

Object[][] data = {

                {"", ""},

        };

String[] headers = {"Employee Code", "Employee First Name"};
JTable table = new JTable(data, headers);

---

如果我读对了，我似乎不知道如何将

哈希表

项添加到

JTable

中，比如

Object[][] data = new Object[c.size()][2];
int row = 0;
for (Object key : c.keySet()) {
    data[row][0] = key;
    Employee emp = (Employee)c.get(key);
    data[row][1] = ...; // Get name from Employee object...
    // Personally, I prefer to assign the Employee object to
    // the column of the row and use a TableCellRenderer to
    // renderer it
}

String[] headers = {"Employee Code", "Employee First Name"};
JTable table = new JTable(data, headers);

应该有用

现在，如果您想在

HashMap

和

TableModel

之间建立更紧密的关系（这样您就可以向表中添加内容，并更新

HashMap

），您需要使用

AbstractTableModel

，并在模型的需求和

HashMap
