使用pandas导出excel 表格时类似这种

其中含有多级表头的情况也就是涉及到表头需要合并单元格（横向及纵向）
1、表头设置

columns = [("xx公司路产月报表","序号","序号"),("xx公司路产月报表","单位","单位"),("xx公司路产月报表","本月使用","份数"),("xx公司路产月报表","本月使用","金额"),("xx公司路产月报表","本月作废","份数"),("xx公司路产月报表","本年累计","使用份数"),("xx公司路产月报表","本年累计","金额"),("xx公司路产月报表","本年累计","作废份数"),("xx公司路产月报表","月末结存","份数")]
df = pd.DataFrame(dep_data_list)
df.columns = pd.MultiIndex.from_tuples(columns)
df.to_excel(excelfile)

结果时这样的

产生的结果会多一列索引，多一行空白行，及纵向的单元格没有被合并

# 列索引不显示
df.to_excel(excelfile,index=False)
# 不被允许，报错NotImplementedError("Writing to Excel with MultiIndex columns and no index ('index'=False) is not yet implemented.",

2、隐藏多余的行

with pd.ExcelWriter(excelfile,engine='xlsxwriter') as writer:
     df.to_excel(writer,sheet_name='报表数据统计')
     writer.sheets['报表数据统计'].set_column(0,0,None,None,{"hidden":True})
     writer.sheets['报表数据统计'].set_row(3,None,None,{"hidden":True})
     writer.save()

结果展示

3、表头纵向合并居中展示、表头字体放大

workbook = load_workbook(excelfile)
sheet = workbook.active
name = workbook.get_sheet_names

sheet.merge_cells('B2:B3')
sheet.merge_cells('C2:C3')
cell = sheet['B1']
font = Font(size=20,bold=True)
cell.font = font
sheet['B2'].alignment = Alignment(horizontal="center", vertical="center")
sheet['C2'].alignment = Alignment(horizontal="center", vertical="center")
workbook.save(excelfile)

结果展示
