用PySimpleGUI和Pandas制作表格

import PySimpleGUI as sg
import pandas as pd

layout = [[sg.Table(values=[], headings=[], max_col_width=25, auto_size_columns=True, justification='left', num_rows=20, alternating_row_color='lightblue', key='-TABLE-')],
          [sg.Button('加载数据', key='-LOAD-'), sg.Button('保存数据', key='-SAVE-'), sg.Button('退出', key='-EXIT-')]]

window = sg.Window('表格示例', layout)

def load_data(filename):
    try:
        data = pd.read_csv(filename)  # 从CSV文件中读取数据
        headings = list(data.columns)  # 获取表头
        values = data.values.tolist()  # 获取数据行
        return headings, values
    except Exception as e:
        sg.popup_error(f'加载数据失败：{str(e)}')
        return [], []

def save_data(filename, headings, values):
    try:
        data = pd.DataFrame(values, columns=headings)  # 创建DataFrame对象
        data.to_csv(filename, index=False)  # 将数据保存为CSV文件
        sg.popup('保存数据成功！')
    except Exception as e:
        sg.popup_error(f'保存数据失败：{str(e)}')

while True:
    event, values = window.read()
    
    if event == sg.WINDOW_CLOSED or event == '-EXIT-':
        break
    
    if event == '-LOAD-':
        filename = sg.popup_get_file('选择要加载的文件', file_types=(('CSV Files', '*.csv'),))
        if filename:
            headings, values = load_data(filename)
            window['-TABLE-'].update(values=values, headings=headings)
    
    if event == '-SAVE-':
        filename = sg.popup_get_file('选择要保存的文件', save_as=True, file_types=(('CSV Files', '*.csv'),))
        if filename:
            save_data(filename, window['-TABLE-'].get_headings(), window['-TABLE-'].get_data())

window.close()
