我正在尝试使用 Ext JS 创建一个简单的网格，它允许我快速浏览和编辑每一行。基本上我想开始编辑一行，点击向下箭头并能够开始编辑下一行。如果我不保存到最后也没关系，但现在当我尝试向下导航到下一个字段时，它告诉我需要先提交或取消编辑。是否有我错过的设置或我只是忽略的东西？我对 Ext JS 还是很陌生，还没有完全理解一切是如何工作或联系在一起的。

这是我的代码：

    <!DOCTYPE html>

    <script type="text/javascript" src="js/ext-4.1.1a/ext-all.js"></script>

        }

        }

好吧，我切换到 cellEditing 而不是 rowEditing，现在它似乎工作正常（也内置了 tab/shift+tab 用法）。
