DataFrame添加行列_dataframe写入excel的时候加一行抬头

# 1. 加载初始dataframe
early_size = pd.read_excel(target_file,'early-bind',index_col=0)
 
# 2. 组织新加入的列的数据
late_size_avg = []
for func_name in workflow_info[workflow_name]:
    late_size_avg.append(np.average(late_size[func_name].dropna()))
 
# 3. 加入一列
early_size['late-size'] = late_size_avg
 
# 4. 加入一行
early_size.loc['total'] = early_size.to_numpy().sum(axis=0) #各列数据相加
early_size.loc['late/early'] = [early_size.loc['total'][-1]/early_size.loc['total'][0],np.nan,1]
 
# 5. 修改各列的排不顺序，并另存为其他文件
early_size[['early-size','late-size','early-time-budget']].to_excel(excel_writer=writer,sheet_name=str(slo))
