Tabular data does not store text direction, only characters. A good grid respects document direction (LTR vs RTL) for chrome and navigation while still rendering cell contents according to Unicode bidirectional rules.
Pipeline tips
- Keep header names stable ASCII slugs in machine contracts; use display labels in apps if needed.
- Avoid visually reordering columns in exports unless consumers expect that order.
- QA mixed numerals and dates in RTL locales, separators vary by region.
