worksheet = workbook.add_worksheet()

#设置粗体格式
bold = workbook.add_format({'bold': 1})

#设置钱币格式
money_format = workbook.add_format({'num_format': '$#,##0'})

#设置日期格式
date_format = workbook.add_format({'num_format': 'mmmm d yyyy'})

#设置宽度
worksheet.set_column(1, 1, 15)

#写入数据
# worksheet.write('A1', 'Item', bold)
# worksheet.write('B1', 'Date', bold)
# worksheet.write('C1', 'Cost', bold)
worksheet.write_row('A1',["Item","Date","Cost"],bold)

#需要写入的数据
expenses = (
    ['Rent', '2013-01-13', 1000],

)

#写入数据开始位置
row = 1
col = 0

for item, date_str, cost in (expenses):
    #将日期格式转为日期对象
    date = datetime.strptime(date_str, "%Y-%m-%d")

    worksheet.write_string(row, col, item)
    worksheet.write_datetime(row, col + 1, date, date_format)
    worksheet.write_number(row, col + 2, cost, money_format)
    row += 1

#写入统计总数公式
worksheet.write(row, 0, 'Total', bold)
worksheet.write(row, 2, '=SUM(C2:C5)', money_format)

workbook.close()
