我正在尝试使用以下给定的方法在选定行的表格列中移动:
//on Enter key press
KeyStroke enter = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);
my_table.getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(enter, "nextColumn");
my_table.getActionMap().put("nextColumn", new AbstractAction() {
@Override
public void actionPerformed(ActionEvent ae) {
if (itemSelected) {
//cost column
if (my_table.editCellAt(my_table.getSelectedRow(), 4)) {
System.out.println("column cost editing...");
}
itemSelected = false;
} else {
if (my_table.isCellEditable(my_table.getSelectedRow(), 4)) {
//qty column
System.out.println("column qty editing...");
my_table.editCellAt(my_table.getSelectedRow(), 6);
//It breaks from here
} else if (my_table.isCellEditable(my_table.getSelectedRow(), 6)) {
//free_qty column
System.out.println("column free_qty editing...");
my_table.editCellAt(my_table.getSelectedRow(), 7);
} else if (my_table.isCellEditable(my_table.getSelectedRow(), 7)) {
//dis % column
System.out.println("column dis % editing...");
my_table.editCellAt(my_table.getSelectedRow(), 8);
} else if (my_table.isCellEditable(my_table.getSelectedRow(), 8)) {
//free_qty column
System.out.println("column free_qty editing...");
DefaultTableModel model = (DefaultTableModel) my_table.getModel();
model.addRow(new Vector());
my_table.setRowSelectionInterval(1, 1);
}
}
}
});
但是，当我在 qty 列 处按 Enter 键时，它不会移动到下一个指定的 free_qty 列。
任何建议都会受到重视。

最佳答案
} else {
if (table.isCellEditable(table.getSelectedRow(), 4)) {
上面的条件始终为真，因为您总是从第四列开始检查。
您真正想要做的是创建一个循环，迭代表中的所有列，从 table.getSelectedColumn() + 1 开始，直到找到下一个可编辑列。
