pysimplegui库中的table控件的用法

PySimpleGUI的Table控件允许你创建表格形式的用户界面元素，用于展示数据。以下是使用`Table`的基本步骤[^1]：

1. **导入库**:

   import PySimpleGUI as sg

2. **定义表头**:

   headings = ['Column 1', 'Column 2', 'Column 3']

3. **初始化表单**:

   layout = [[sg.Table(values=[], headings=headings, num_rows=10, key='-TABLE-')]]

4. **创建窗口**:

   window = sg.Window('Table Example', layout)

5. **填充数据** (你可以通过`update_table`函数添加或更新数据):

   table_data = [['Row 1 Value 1', 'Row 1 Value 2', 'Row 1 Value 3'],
                 ['Row 2 Value 1', 'Row 2 Value 2', 'Row 2 Value 3']]
   window['-TABLE-'].update(table_data)

6. **事件循环**:

   event, values = window.read()

7. **关闭窗口**:

   if event == sg.WINDOW_CLOSED or event == 'Cancel':
       window.close()

完整示例:

import PySimpleGUI as sg

headings = ['Column 1', 'Column 2', 'Column 3']
layout = [[sg.Table(values=[], headings=headings, num_rows=10, key='-TABLE-')]]

window = sg.Window('Table Example', layout)

table_data = [['Row 1 Value 1', 'Row 1 Value 2', 'Row 1 Value 3'],
              ['Row 2 Value 1', 'Row 2 Value 2', 'Row 2 Value 3']]

window['-TABLE-'].update(table_data)

event, values = window.read()

if event == sg.WINDOW_CLOSED or event == 'Cancel':
    window.close()
