使用openpyxl在excel工作表中打印python数据帧时如何跳过默认数据帧索引

Question

I am trying to print a pandas data frame in an excel sheet, using openpyxl. Until now I have accomplished to print the data frame with the default index. My question is, how to print it without the default index. The following example script generates Table 1 and I would like to know what I need to modify in order to come up with Table 2 .

import pandas as pd
from openpyxl.utils.dataframe import dataframe_to_rows

df = pd.DataFrame((1,2,3,4,5,6))
wb = openpyxl.Workbook()           
sheet = wb.active 
rows = dataframe_to_rows(df)

for r_idx, row in enumerate(rows, 1):
    for c_idx, value in enumerate(row, 1):
         sheet.cell(row=r_idx+1, column=c_idx, value=value)

wb.save('book1.xlsx')

Table 1

  0

0 1
1 2
2 3
3 4
4 5
5 6

Table 2

1
2
3
4
5
6

Answer 1

Unless you have a more elaborated requirement, it's quite easier to go straight with pandas.DataFrame.to_excel , which already integrates with openpyxl .

df.to_excel('book1.xlsx')

To drop the index, just add:

df.to_excel('book1.xlsx', index=False)
