[英]How can I sort Columns by Row values?
There are [too] many examples online of how to sort the Rows of a JTable by Column values. 在线上有太多关于如何按列值对JTable的行进行排序的示例。
Currently I am doing this by implementing AbstractTableModel
and overridding getColumnClass
to return the actual class of the data. 目前,我正在通过实现
AbstractTableModel
并重写getColumnClass
来返回数据的实际类来进行此操作。 Then calling setAutoCreateRowSorter
. 然后调用
setAutoCreateRowSorter
。

1) extract all value from TableHeader
to the shortable Array (could be method in AbstractTableModel
) 1)提取所有值
TableHeader
到卖空阵列(可能是方法AbstractTableModel
)
2) loop inside array and call 2)在数组内部循环并调用
TableColumn column = table.getColumnModel().moveColumn(columnIndex, newIndex);
3) for all methods that used Model vs View (and vice versa) is required add 3)对于使用模型与视图(反之亦然)的所有方法,必须添加
table/model#convertXxxIndexToXxx
4) for reset you have to create method in AbstractTableModel
by calling 4)对于重置,您必须通过调用在
AbstractTableModel
创建方法
fireTableDataChanged(); or fireTableStructureChanged(); // not sure in this case
5) notice about above two fireTableXxxXxx 5)关于以上两个fireTableXxxXxx的通知
