我有一个 Pandas 数据框,我将其写入xslx文件,并希望在该数据上添加一个表。我还想保留已经编写的标题,而不是再次添加它们。那可能吗?

例子:

import pandas as pd
import xlsxwriter as xw

# random dataframe
d = {'one' : pd.Series([1., 2., 3.], index=['a', 'b', 'c']), 'two' : pd.Series([5., 6., 7., 8.], index=['a', 'b', 'c', 'd'])}
df = pd.DataFrame(d)


# write data to file
writer = pd.ExcelWriter("test.xlsx", engine='xlsxwriter')
df.to_excel(writer,"sheet without table")
df.to_excel(writer,"sheet with table")
df.to_excel(writer,"sheet with table and header")

# get sheets to add the tables
workbook  = writer.book
worksheet_table = writer.sheets['sheet with table']
worksheet_table_header = writer.sheets['sheet with table and header']

# the range in which the table is
end_row = len(df.index)
end_column = len(df.columns)
cell_range = xw.utility.xl_range(0, 0, end_row, end_column)


# add the table that will delete the headers
worksheet_table.add_table(cell_range,{'header_row': True,'first_column': True})

######################################
# The hack

# Using the index in the Table
df.reset_index(inplace=True)
header = [{'header': di} for di in df.columns.tolist()]
worksheet_table_header.add_table(cell_range,{'header_row': True,'first_column': True,'columns':header})

writer.save()

最佳答案

hack/解决方法是唯一的选择(如@jmcnamara所示)。简而言之是:

import pandas as pd
import xlsxwriter as xw

# random dataframe
d = {'one' : pd.Series([1., 2., 3.], index=['a', 'b', 'c']), 'two' : pd.Series([5., 6., 7., 8.], index=['a', 'b', 'c', 'd'])}
df = pd.DataFrame(d)


# write data to file
writer = pd.ExcelWriter("test.xlsx", engine='xlsxwriter')
df.to_excel(writer,"sheet with table and header")

# get sheets to add the tables
workbook  = writer.book
worksheet_table_header = writer.sheets['sheet with table and header']

# the range in which the table is
end_row = len(df.index)
end_column = len(df.columns)
cell_range = xw.utility.xl_range(0, 0, end_row, end_column)

# The hack

# Using the index in the Table
df.reset_index(inplace=True)
header = [{'header': di} for di in df.columns.tolist()]
worksheet_table_header.add_table(cell_range,{'header_row': True,'first_column': True,'columns':header})

writer.save()
