如何使JTable单元格默认为覆盖模式

你应该可以通过创建自己的 TableCellEditor ,可以使用 setCellEditor()

你可能会发现 Table Select All Editor 有帮助。

我已经实现了下面的方法[addDeletePreviousOnEditBehavior],效果很好!注意你需要用一些 TableCellEditor . 为此,请添加以下代码:

JTable table=new JTable();
JTextField field=new JTextField();
addDeletePreviousOnEditBehavior(field);
table.setCellEditor(new DefaultCellEditor(field));

方法是:

public static void addDeletePreviousOnEditBehavior(final JComponent field) {

    field.addFocusListener(new FocusListener() {

        @Override
        public void focusGained(FocusEvent fe) {
            field.putClientProperty(DELETE_ON_EDIT, true);
        }

        @Override
        public void focusLost(FocusEvent fe) {
        }
    });

    field.addKeyListener(new KeyListener() {

        @Override
        public void keyTyped(KeyEvent ke) {
        }

        @Override
        public void keyPressed(KeyEvent ke) {
            if ((!(ke.isActionKey()
                    || isSpecial(ke.getKeyCode())))
                    && ((Boolean) field.getClientProperty(DELETE_ON_EDIT))) {
                System.out.println("Key:" + ke.getKeyCode() + "/" + ke.getKeyChar());
                field.putClientProperty(DELETE_ON_EDIT, false);
                if (field instanceof JFormattedTextField) {
                    ((JFormattedTextField) field).setValue(null);
                }
                if (field instanceof JTextComponent) {
                    ((JTextComponent) field).setText(null);
                }

            }
        }

        @Override
        public void keyReleased(KeyEvent ke) {
           // do nothing
        }
    });
}
