python - 使用 Python 将 Pandas DataFrame 导出为 PDF 文件

Question

在 Pandas 中为数据框生成 PDF 的有效方法是什么？

Answer 1

首先使用 matplotlib 绘制表格，然后生成 pdf

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.backends.backend_pdf import PdfPages

df = pd.DataFrame(np.random.random((10,3)), columns = ("col 1", "col 2", "col 3"))

fig, ax =plt.subplots(figsize=(12,4))
ax.axis('tight')
ax.axis('off')
the_table = ax.table(cellText=df.values,colLabels=df.columns,loc='center')
