import markdown  # Import the Markdown module to use its functionality

# Define a simple Markdown text
md_text = """
# Hello World

This is a paragraph with **bold text** and *italic text*.
"""

import markdown  # Import the Markdown module

# Enable the tables extension
md_text = """
| Header 1 | Header 2 |
|----------|----------|
| Row 1    | Row 1    |
| Row 2    | Row 2    |
"""

# Convert the Markdown text with table support
html_output = markdown.markdown(md_text, extensions=['tables'])  # Include the tables extension for Markdown parsing

print(html_output)  # Show the resulting HTML output with a table

In this scenario, we use the tables extension of the Markdown module to handle table formatting. This illustrates how to enhance Markdown’s capabilities when necessary.
