table,CellEdit的问题，为什么我改变comboBox的内容，而表格的内容不变呢？代码如下：

Question

不用这么麻烦
DefaultTableColumnModel dcm = (DefaultTableColumnModel)table.getColumnModel();
TableColumn column = dcm.getColumn(1);
// Use the combo box as the editor in the "Next T" column.
DefaultCellEditor editor = new DefaultCellEditor(jcmbNextT);
column.setCellEditor(editor);

Answer 1

可是如果我要用JScrollBar 怎么办了？

Answer 2

呵呵,改了一点你的程序,现在应该可以了.
