我试图在 tree.Panel 上实现可锁定功能，所以我从 grid.Panel 借来

Ext.tree.Panel(Ext.grid.Panel, ['bothCfgCopy','normalCfgCopy','lockedCfgCopy']);

但现在我的网格列是对象，即树上的 column.$className。Panel 将返回一个对象，因为它们已被转换。我现在如何隐藏列，因为所有功能（例如 hide()、setVisible() 都已丢失）？

提前致谢

It might not still be relevant, but here's an example of a buffering locking grid.

You can set buffering to false and use as is, or you can use it as a guideline for you current implementation.
