我正在尝试创建一个具有可变列数的 Treeview，当列数使 TreeView 比主窗口宽时，它允许水平滚动。现在我已经实现了垂直和水平滚动条。永远不会启用水平滚动条，因为包含它的 TreeView 和 Frame 都展开以适应所有列，而多余的列会从主窗口中流出。但是，无论行数如何，TreeView 的高度都不会改变。如果有人可以帮助我模仿水平的行为，将不胜感激。
TreeView 太大，看不到垂直滚动条或水平滚动条的右端
TreeView 适合，两个滚动条都可以看到
我试图在下面包含相关代码：
class Application(Frame):

Frame.__init__(self, master)

header = tabDict['header']
data = tabDict['data']
self.tree["columns"] = header
self.tree['show'] = 'headings'
self.tree.delete(*self.tree.get_children())
for head in header:
self.tree.column(head, width=10, anchor='c')
self.tree.heading(head, text=head)
#print(data)
for j in range(len(data)):
row = list(data[j])
self.tree.insert("",'end',text=str(j),values=row)

#self.frame.delete('1.0',END)
d = self.dbVar.get()
t = self.tableVar
