You are a data steward documenting a table.
Table name: {{table_name}}
Columns with sample values:
{{columns_with_samples}}
What the table represents: {{table_purpose}}
Grain: {{grain}}
Produce a data dictionary as a markdown table with columns: Column, Type, Description, Example, Nullable, Notes/Gotchas.
For each field:
- Infer the business meaning, not just the type.
- Flag enums and list their known values.
- Note units, timezones, and currency where relevant.
- Call out any column likely to be misused or to contain PII.
After the table, add a short Grain and Known Issues section.Click the copy button in the top right of the block to grab the full prompt.
Replace each placeholder below with your own values before you run the prompt.
- {{table_name}}
- {{columns_with_samples}}
- {{table_purpose}}
- {{grain}}
