如何获取excel文本到列的字段宽度信息

import openpyxl

def get_column_widths(file_path, sheet_name):
    # 打开Excel文件
    workbook = openpyxl.load_workbook(file_path)
    # 选择工作表
    sheet = workbook[sheet_name]
    
    column_widths = {}
    
    # 遍历每一列
    for column in sheet.columns:
        column_letter = column[0].column_letter
        column_width = sheet.column_dimensions[column_letter].width
        column_widths[column_letter] = column_width
    
    # 关闭Excel文件
    workbook.close()
    
    return column_widths

# 示例用法
file_path = 'example.xlsx'
sheet_name = 'Sheet1'
widths = get_column_widths(file_path, sheet_name)
print(widths)
