我有一个panda数据帧,我写入xslx文件,并希望在该数据上添加一个表.我还想保留我已经编写的标题,而不是再次添加它们.那可能吗?
例:
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()
解决方法:
黑客/解决方案是唯一的选择(从@jmcnamara可以看出).简而言之就是:
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()
