📄 AddContentToPage.is_table in src/backend/base/langflow/components/Notion/add_content_to_page.py

✨ Performance Summary:

• Speed Increase: 📈 13% (0.13x faster)
• Runtime Reduction: ⏱️ From 883 microseconds down to 780 microseconds (best of 118 runs)

📝 Explanation and details

Certainly! Here's a more optimized version of your program.

Changes made for optimization.

1. Cells Processing.

   • Instead of initially stripping each cell and then filtering out the empty ones in two separate steps, I've combined them into one list comprehension to reduce redundancy.

2. Separator Check.

   • Simplified the check for a separator row using all(cell == '-' * len(cell) for cell in cells) which ensures each cell in the second row only contains hyphens without repeatedly converting the string to sets.

Why This Might Be Faster.

These optimizations focus on reducing the number of iterations and memory operations needed, which might slightly improve performance for large inputs.
