使用 Reportlab 添加数据框到 PDF python

Question

我正在尝试使用实验室报告以 pdf 格式显示我的日期框架。到目前为止我已经弄清楚我想要什么但我不知道如何添加索引所以它丢失了。我的 pdf 看起来像这样：我的数据框：

            00-04  04-08  08-12  12-16  16-20  20-24
2017-12-09  17671  16443  14300  15317  16398  16398
2017-12-10  16632  17611  16486  10562  10562  13014
2017-12-11  11355      0      0      0   8569  11697

我的代码：

from reportlab.lib.styles import getSampleStyleSheet
from reportlab.platypus import *
from reportlab.lib import colors
import pandas as pd
import random

PATH_OUT = "C:\"

elements = []
styles = getSampleStyleSheet()
doc = SimpleDocTemplate("Analysis_Lists.pdf", pagesize=A3, rightMargin=30,leftMargin=30, topMargin=30,bottomMargin=18)
elements.append(Paragraph("Wind Park Available Flex Neg", styles['Title']))

data = [[random.random() for i in range(1,4)] for j in range (1,8)]
df = resultado(lista,df_output,labels)
lista = [df.columns[:,].values.astype(str).tolist()] + df.values.tolist()

ts = [('ALIGN', (1,1), (-1,-1), 'CENTER'),
     ('LINEABOVE', (0,0), (-1,0), 1, colors.black),
     ('LINEBELOW', (0,0), (-1,0), 1, colors.black),
     ('FONT', (0,0), (-1,0), 'Times-Bold'),
     ('LINEBELOW', (0,-1), (-1,-1), 1, colors.black),
     ('BACKGROUND',(1,1),(-2,-2),colors.white),
     ('TEXTCOLOR',(0,0),(1,-1),colors.black)]

table = Table(lista, style=ts)
s = getSampleStyleSheet()
s = s["BodyText"]
s.wordWrap = 'CJK'
Explanation = [["The lost HT flex in the last week for 50 Hz SRL is ."],
["The lost HT flex in the last week for Tennet SRL is "],
["The lost HT flex in the last week for Amprion SRL is "],
]

data2 = [[Paragraph(cell, s) for cell in row] for row in Explanation]
e=Table(data2,spaceAfter=20)

elements.append(table)
elements.append(e)

我已经添加了列和值，但不确定如何添加索引，我的索引是日期时间戳：

l = df.index[:,].strftime('%Y/%m/%d')
l = l.tolist()
l = [u'2017/12/09', u'2017/12/10', u'2017/12/11']

有人可以提示我如何继续这个过程吗？我对报告实验室不熟悉。任何帮助或建议都将非常有用我已阅读 Report Lab 用户指南

Answer 1

如评论中所述，我认为 PDF 问题是 "Red-Herring"。我认为真正的问题只是将索引放入列中。

df_2 = df.reset_index().rename(columns = {'index':'date'}) 
#.rename is just renaming 'index' into 'date'. you can put anything you want in there

现在将 df2 传递给 lista 而不是 df。

其余代码将按预期工作。
