这个呢：
https://kb.kaifa99.com/others/post_14232521 我找到一种解决办法，虽然貌似有点繁琐，你自己看着办吧。。

self.tree.heading(3, text='Age')
self.iid = self.tree.insert("", 'end', text ="item_1", values =("Bill", "M", "25"),
tags=('d_click', 'test'))# 为每条item添加tags，然后利用该tags来触发事件，如双击

self.tree.tag_bind('d_click', '<Double-1>', lambda e:self.entry_popup(e))

self.tree.insert('', str(focused), values=x)
self.tree.delete(focused)# 删掉原有的
