Frequently Asked Questions

What's the maximum table size?

This tool can handle tables with up to 50 columns and 1000 rows. For very large tables, processing may take a few seconds.

How does auto-detection work?

Auto-detection analyzes cell content: numbers are right-aligned, short text is centered, and long text is left-aligned.

Does this support complex Markdown?

This tool focuses on basic table alignment. Inline formatting like **bold** and *italic* is preserved but doesn't affect alignment.

Formulas & Assumptions

Column width calculation: max(cell_content_length) + 2 padding spaces

Auto-alignment rules:

Numeric cells (≥80% numeric): Right-aligned
Short text (≤15 chars): Center-aligned
Long text (>15 chars): Left-aligned

Padding: Minimum 1 space on each side of cell content
