Answer 1

In case you have 0.22, you must do pd.io.formats.excel.header_style = None. Check this git page out.

Answer 2

You are trying to change the formatting of the header so you should first reset the default header settings

pd.core.format.header_style = None

Then apply the formatting as required

format = workbook.add_format()
format.set_align('center')
format.set_align('vcenter')

worksheet.set_column('A:C',5, format)

here is complete working code

d=pd.DataFrame({'a':['a','a','b','b'],
               'b':['a','b','c','d'],
               'c':[1,2,3,4]})
d=d.groupby(['a','b']).sum()

pd.core.format.header_style = None

writer = pd.ExcelWriter('pandas_out.xlsx', engine='xlsxwriter')
workbook  = writer.book
d.to_excel(writer, sheet_name='Sheet1')

worksheet = writer.sheets['Sheet1']

format = workbook.add_format()
format.set_align('center')
format.set_align('vcenter')

worksheet.set_column('A:C',5, format)
writer.save()
