我已经创建了一个 TreeView，但我希望能够在调用特定函数时隐藏某些列。所以这个 TreeView 最初是创建的，但是当我调用一个函数时，可以说除了 [trackArtist] 之外的所有列都被隐藏了。我该怎么做呢？我可以通过在函数中重写 TreeView 的部分(我想显示的列)来让它工作，但这似乎非常多余。
def some_function(self):
self.tree = ttk.Treeview(self.stationBuilderMenuMiddleFrame)
ttk.Style().configure("displayField", background="#850664", foreground="#000000", fieldbackground="#FFFFFF")
ysb = ttk.Scrollbar(self.stationBuilderMenu, orient=tk.VERTICAL, command=self.tree.yview)
xsb = ttk.Scrollbar(self.stationBuilderMenu, orient=tk.HORIZONTAL, command=self.tree.xview)
self.tree.configure(yscrollcommand=ysb.set)
self.tree.configure(xscrollcommand=xsb.set)
self.tree["columns"]=("trackNumber", "trackTitle", "artistCat", "artistDisplay", "trackArtist", "album",
"albumLabel", "composer", "year", "trackDuration", "albumAsin", "albumItunes", "ISRC",
"filename", "albumCoverName", "notes")
self.tree.column("trackNumber", stretch=0, anchor=N)
self.tree.column("trackTitle", stretch=0, anchor=N)
self.tree.column("artistCat", stretch=0, anchor=N)
self.tree.column("artistDisplay", stretch=0, anchor=N)

self.stationBuilderMenuMiddleFrame.rowconfigure(0, weight=1)
self.stationBuilderMenuMiddleFrame.columnconfigure(0, weight=1)
这是我拼凑的破解代码。效果不是很好。

请您参考如下方法:
你应该可以使用
self.tree["displaycolumns"]=("artistCat", "artistDisplay")
发现于 Documentation .
要显示除一个以外的所有内容，您可以在 for 循环中构建它
exclusionlist=[...]
displaycolumns=[]
for col in tree["columns"]:
if not "%s"%col in exclusionlist:
displaycolumns.append(col)
tree["displaycolumns"]=displaycolumns
在下面找到不会弄乱数据的工作代码。 仅使用 tree["displaycolumns"]=[...]
