Question

我使用xlsxwriter模块格式化excel文件中的所有列：

def to_excel(video_report, feed):
    # Create a Pandas Excel writer using XlsxWriter as the engine.
    writer = pd.ExcelWriter('daily_report.xlsx', engine='xlsxwriter')

    # Convert the dataframe to an XlsxWriter Excel object.
    video_report.to_excel(writer, sheet_name='Video Overview', na_rep="-")

    # Get the xlsxwriter objects from the dataframe writer object.
    workbook = writer.book
    worksheet = writer.sheets['Video Overview']

    # Add some cell formats.
    integer = workbook.add_format({'num_format': '0', 'align': 'center'})
    decimal = workbook.add_format({'num_format': '0.00', 'align': 'center'})
    percentage = workbook.add_format({'num_format': '0.0%', 'align': 'center'})

    zebra = workbook.add_format({'bold': True})

    worksheet.set_column('B:B', 13, integer)
    worksheet.set_column('C:C', 17, percentage)
    worksheet.set_column('D:D', 19, percentage)
    worksheet.set_column('E:E', 15, integer)
    worksheet.set_column('F:F', 15, percentage)
    worksheet.set_column('G:G', 15, decimal)
    worksheet.set_column('H:H', 13, integer)
    worksheet.set_column('I:I', 13, integer)
    worksheet.set_column('J:J', 13, integer)
    worksheet.set_column('K:K', 13, integer)
    worksheet.set_column('L:L', 13, integer)

    worksheet.set_row(3, 20, zebra)

    feed.to_excel(writer, sheet_name='Feed Position', na_rep="-")

    workbook1 = writer.book
    worksheet1 = writer.sheets['Feed Position']

    integer = workbook1.add_format({'num_format': '0', 'align': 'center'})

    worksheet1.set_column('B:HU', 4, integer)

    writer.save()

我想在我的行中添加斑马条纹，但我似乎无法找到一种逐行格式化的方法，而不会覆盖我的列格式。作为测试，我创建了一个粗体格式并将其应用到第3行，但它覆盖了我的列格式是否可以逐行添加格式而不会按列格式覆盖我的列？或者也许有斑马条纹的成语可以避免逐行格式化？

编辑：我认为我的情况变得更加困难，因为数据已经通过pandas函数写入excel。反正这是否会使行和列的格式化更容易？

修改网址http://xlsxwriter.readthedocs.org/en/latest/example_conditional_format.html

中的XLSXWriter示例代码

我建议您在使用测试中的行值迭代数据时进行格式化。例如......

编写数据时：

###############################################################################
#
# Example 9.
#
caption = ('Rows with odd numbers are in light red. '
           'Rows with even numbers are in light green.')

# Write the data.
worksheet9.write('A1', caption)

for row, row_data in enumerate(data):
    if row%2 == 0:
        worksheet9.write_row(row + 2, 1, row_data, format1)
    else:
        worksheet9.write_row(row + 2, 1, row_data, format2)

写完数据后：

###############################################################################
#
# Example 10.
#
#
caption = ('Rows with odd numbers are in light red. '
           'Rows with even numbers are in light green.')
#
# Write the data.
worksheet10.write('A1', caption)
##
for row, row_data in enumerate(data):
    worksheet10.write_row(row + 2, 1, row_data)
##
# Write a conditional format over a range.
for row, row_data in enumerate(data):
    if row%2 == 0:
        worksheet10.set_row(row + 2, None, format1)
    else:
        worksheet10.set_row(row + 2, None, format2)

Per https://support.office.com/en-in/article/Apply-shading-to-alternate-rows-in-a-worksheet-a443b0f5-2025-42f6-9099-5de09c05e880，Microsoft提供了两种实现交替行格式的方法：条件格式或表样式＆＃34;带状行＆＃34;。

公式=MOD(ROW(),2)=0的条件格式化已完成，但Excel 2013无法解释它。

# Write a conditional format over a range DOES NOT WORK
worksheet1.conditional_format('A1:K12', {'type': 'cell',
                                         'criteria': '=MOD(ROW(),2)',
                                         'value': 0,
                                         'format': format1})

# Write another conditional format over the same range also DOES NOT WORK
worksheet1.conditional_format('A1:K12', {'type': 'cell',
                                         'criteria': '=MOD(ROW(),2)',
                                         'value': 1,
                                         'format': format2})

除了使用xlsxwriter进行列格式化之外，还要逐行应用格式
