将Python Tkinter-Treeview中的行提取到Pandas数据框中

import tkinter as tk
from tkinter import ttk
import pandas as pd

window = tk.Tk()
tree = ttk.Treeview(window)

tree["columns"] = ("column1", "column2", "column3")
tree["show"] = "headings"  # 隐藏首列空白列

# 添加列名
tree.heading("column1", text="Column 1")
tree.heading("column2", text="Column 2")
tree.heading("column3", text="Column 3")

# 添加数据
tree.insert("", "end", values=("Value 1", "Value 2", "Value 3"))

df = pd.DataFrame(columns=["Column 1", "Column 2", "Column 3"])

def extract_rows():
    selected_items = tree.selection()  # 获取选中的行
    for item in selected_items:
        values = tree.item(item, "values")  # 获取行的值
        df.loc[len(df)] = values  # 将值添加到数据框中

button = tk.Button(window, text="Extract Rows", command=extract_rows)
button.pack()

window.mainloop()
