如何建立 Pandas DataFrame 的 PNG 映像？

<code class="python">import matplotlib.pyplot as plt
import pandas as pd
from pandas.plotting import table

# Hide axes and create a subplot
fig = plt.figure()
ax = fig.add_subplot(111, frame_on=False)
ax.xaxis.set_visible(False)
ax.yaxis.set_visible(False)

# Plot the DataFrame without the axes
table(ax, df)

# Remove any text that may still be visible
plt.text(0, 0, '')
ax.get_xaxis().set_ticks([])
ax.get_yaxis().set_ticks([])

# Save the plot as a PNG file
plt.xticks([])
plt.yticks([])

plt.savefig('dataframe_image.png', bbox_inches='tight')
plt.close(fig)</code>
