      @Override
      public void keyPressed(KeyEvent e) {
          if (e.getKeyCode()==KeyEvent.VK_ENTER) {
               rowCount = this.table.getSelectedRow() + 1;

推荐答案

首先，我鼓励您使用键绑定API ，KeyListener是低级API，可以在看到事件之前先将其消耗掉.

Firstly, I would encourage you to use the key bindings API, KeyListener is a low level API and events can be consumed before you ever see them.

要更改/设置JTable中的行选择，应使用 JTable#setRowSelectionInterval

To change/set the row selection in a JTable, you should use JTable#setRowSelectionInterval

InputMap im = getInputMap(WHEN_FOCUSED);
im.put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "enter");
ActionMap am = getActionMap();
am.put("enter", new AbstractAction() {
    @Override
    public void actionPerformed(ActionEvent e) {
        int rowCount = table.getSelectedRow() + 1;
        tModel.insertRow(rowCount,new Object[]{"", "","",""});
        table.setRowSelectionInterval(rowCount, rowCount);
    }
});
