嗨，我想实现一个带有水平和垂直滚动条的可编辑表，所以我选择了富面的扩展表，并想编辑这个表中的数据，所以我选择了就地输入和就地选择，如果我工作得很好少于 30 行，如果我有更多的行说 600 行.....渲染页面太慢了
没有就地选择，我只是尝试显示它工作得很好，所以我认为原因如下，因为每行有 6 个就地选择，所以它太慢了，因为它需要加载 600*6 =3600 选择下拉并且对于每个下拉菜单，它将进入模态类以获取每个下拉菜单的选择列表。
在这 600 行的每一行中重复这 6 个下拉菜单......那么有什么方法可以提高性能并使用这个解决方案，或者有什么好的解决方案吗？
有没有办法将下拉选项存储在富面孔客户端的一个变量中并在同一页面上重新使用？
