### Why is this important?
Assistive technologies use structural elements (`<th>`, `<caption>`) and attributes (`summary`, `scope`, `header`) to help users navigate and understand data tables.
Including these features in layout tables makes the purpose of the table unclear and harms the user experience.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* If the table is a data table, use a valid `role=""` attribute
* **Or**, if a table is used for layout, use CSS-based layouts instead
* **Or**, if a layout table must be used, remove any `<th>` and `<caption>` elements and `summary`, `scope`, and `header` attributes
