tkinter：如何在我的树状视图中添加水平滚动条？

Question

您好，我已经创建了一个仪表板，它有一个垂直滚动条，但水平滚动条不适合我？垂直滚动条工作正常。当我运行代码时，垂直滚动条工作正常，但水平条根本不移动。我如何让它工作

以下是我的代码片段

垂直滚动条工作正常

vsb = ttk.Scrollbar(root, orient="vertical", command=tree.yview)
vsb.place(x=320, y=45, height=200 + 180)
tree.configure(yscrollcommand=vsb.set)

然而，当我为水平方向添加代码时，它不会

hsb = ttk.Scrollbar(root, orient="horizontal", command=tree.xview)
hsb.place(x=320, y=445)
tree.configure(xscrollcommand=hsb.set)

请参阅下面的完整代码

tablename = 'list_all'

df = df.astype(int)
for i in range(1,len(df.columns)+1):
    df[df.columns[i-1]] = df[df.columns[i-1]].apply(lambda x : "{:,}".format(x))

df.reset_index(inplace=True)
rows = df.values.tolist()
