Markdown Table Formatter
Automatically formats Markdown tables with proper column alignment.
Features
- Auto-formatting - Tables are formatted after Write/Edit operations on .md files
- Alignment support - Left (
:---), center (:---:), and right (---:) - Unicode aware - Handles emoji and CJK characters correctly
- Code preservation - Preserves markdown inside inline code blocks
How It Works
The PostToolUse hook triggers after file edits:
- Detects if the file is Markdown (.md, .mdx)
- Parses all tables in the file
- Calculates column widths (accounting for hidden markdown symbols)
- Pads cells for alignment
- Writes formatted content back
Table Syntax
| Left | Center | Right |
|:-----|:------:|------:|
| A | B | C |
Requirements
For best results with CJK/emoji characters:
pip install wcwidth
