Question

我正在尝试将数据帧写入excel并且还使单元格宽度（20）并尝试隐藏网格线。到目前为止，我确实喜欢：

writer = ExcelWriter('output.xlsx')

df.to_excel(writer,'Sheet1')
writer.save()


worksheet = writer.sheets['Sheet1']

# Trying to set column width as 18
worksheet.set_column(0,3,18)   
#the data frame has 2 columns and a row  - in xls it converts them to 3 columns

worksheet.hide_gridlines()
# I tried with option 2 - but this hides only the column grids, I mean the row(in data fram now became column A - it still has grid lines) 

writer.save()

我的数据框架如下：

                              Col1      Col2
  Time 
   2011-01-01 01:00:00        4345        0.444

   2011-01-01 11:00:00        443         7.4

这是错误的方式吗？我没有看到输出文件中的更改。我在这做错了什么？有没有办法命名我的行标题？

下面。当试图隐藏网格线时。行（在数据框[＆＃39;时间]）现在excel中的列A仍然具有网格。

IIUC，set_column宽度你实际上写了df两次;正确的工作流程应该是以下（编辑：添加engine关键字）：

import pandas as pd

writer = pd.ExcelWriter('output.xlsx', engine='xlsxwriter')

df.to_excel(writer,'Sheet1')

worksheet = writer.sheets['Sheet1']

# Trying to set column width as 18
worksheet.set_column(0,3,18)   
#the data frame has 2 columns and a row  - in xls it converts them to 3 columns

worksheet.hide_gridlines()
# I tried with option 2 - but this hides only the column grids, I mean the row(in data fram now became column A - it still has grid lines) 

writer.save()

这应该正确设置列宽。如果您不希望在输出中包含索引Time列，则应设置：

df.to_excel(writer,'Sheet1',index=False)

如果您之前已设置：

df.set_index = 'Time'

当您绘制完整的数据帧时，网格问题实际上仍然存在。我认为当前ExcelWriter对象不支持hide_gridlines()选项的索引，但我不知道它是否是错误。

编辑：感谢评论，这不是错误。
