How to get value of a JTable cell during edit
提问by Mark09
The solution I have seen so far is listen cell change i.e.
到目前为止，我看到的解决方案是监听单元更改，即
TableModelListener tableModelListener = new TableModelListener() {
@Override
public void tableChanged(TableModelEvent e) {
if (e.getType() == TableModelEvent.UPDATE) {
row = e.getFirstRow();
col = e.getColumn();
// do something
}
}
};
But I need to get the cell value, selectedRow & selectedColumn when typing, and before hitting enter. How to do it?
但是我需要在键入时以及在按 Enter 之前获取单元格值 selectedRow 和 selectedColumn。怎么做？

Use a DocumentListener, illustrated here, or a DocumentFilter, seen here, in your TableCellEditor, shown here.
使用 a DocumentListener,此处说明，或 a DocumentFilter,此处看到，在您的TableCellEditor，此处显示。

HINT :
暗示 ：
if (jTable1.getCellEditor() == null) {
System.out.println("Not Edited");
} else {
System.out.println(jTable1.getValueAt(jTable1.getSelectedRow(),jTable1.getSelectedColumn()));
}
where jTable1 is your JTable Name
其中 jTable1 是您的 JTable 名称

Use TableCellListenerfor listening to the changes in the TableModel. By using this you can get the row-index, column-index, old-valueand new-valueof the edited cell in the table.
使用TableCellListener来监听TableModel. 通过使用这个你可以得到row-index，column-index，old-value并new-value在表中编辑的单元格的。
