试图弄清楚如何在tkinter的树景，但最后一点撞到了墙上。我在将数据从最后一列移动到第一列时遇到了一些问题。代码注释中的进一步说明。希望这里的任何人都能为我指明正确的方向。

from tkinter import ttk, Button, Entry, Label, Tk, Scrollbar, Frame
root = Tk()
root.geometry("800x600")
my_frame = Frame(root)
my_frame.pack()
# some value's so interperter doesn't freak out
a = 10
b = 30

# list representing stuff from database query return
list_data = [(a, b, c, 1), (a, b, c, 2), (a, b, c, 3), (a, b, c, 4),

(a, b, c, 14),]

tree["show"] = "headings"
for col in range(len(cols)):
tree.column(col, width=100, anchor="c")
tree.heading(col, text=cols[col])
#----------------------------------------------------------------------
# want to shift column 4's data representing rowid to column 1
# expected it just to be values=list_data[data-1] but that only shifts
# the data vertical inside column 4

tree.insert("", "end", text=list_data[data], values=list_data[data])

side_scroller.pack(side="right", fill="y")
tree.configure(yscrollcommand=side_scroller.set)

我已经花了很长时间才发现一些有用的东西，虽然不漂亮，但如果你知道更好的方法，可以随时发布改进。也许这将为某人省去一些挫折感作为起点。
