# Convert the dataframe to an XlsxWriter Excel object. Note that we turn off
# the default header and skip one row to allow us to insert a user defined
# header.

# Get the xlsxwriter workbook and worksheet objects.
workbook  = writer.book

# Add a header format.

    'bold': True, # 字体加粗
    'text_wrap': True, # 是否自动换行
    'valign': 'top',  #垂直对齐方式
    'align': 'right', # 水平对齐方式
    'fg_color': '#D7E4BC', # 单元格背景颜色
    'border': 2}) # 单元格边框宽度

# Close the Pandas Excel writer and output the Excel file.
