# Table Design Patterns

> Design patterns for building reliable Table workflows.

Use this pattern to keep Table workflows readable, rerunnable, and easy to debug.

## Recommended pattern

1. Put source data in text columns.
2. Add one computed column per logical step.
3. Map every computed column to explicit source columns.
4. Keep checks and score columns close to the outputs they evaluate.
5. Rerun stale cells before reading the score.
6. Save versions at meaningful checkpoints.
7. Use Analytics when you need request-level debugging.
