Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Expandable row | Choose expandable row when the main surface is a table or list and the extra content is owned by one row. | The expand control names the affected row, exposes expanded state, and controls only that row's detail region. | WAI table guidance supports preserving header and cell relationships in data tables. |
| Table | Choose table when each row represents one record and each column represents the same attribute for every row. | The table caption or nearby heading names the dataset and purpose, not just Table. | WAI table guidance supports semantic headers, data cells, captions, scope, and complex header associations. |
