Column width rules
- A column is as wide as its widest cell
- Each column is measured independently
Comment and blank line rules
- Comment and blank lines keep their place and content
- Which lines count as comments or blanks
Display width rules
- Each code point is zero, one or two columns wide
- String width is the sum of its code point widths
Graceful degradation
- Unparseable input is returned unchanged
Indentation rules
- Tables are re-indented from scratch
