9. Avoid Using Tables for Layout
Tables have a very specific meaning and functionality in Web content. Using tables to create multi-column layouts creates a number of issues for users of diverse abilities as well as design issues for responsive layout. Whenever possible, use Drupal to customize the page to have multiple columns of content rather than using tables to create a visual layout with multiple columns.
- Use the page layout features of Drupal to create multi-column page layouts
- Do not use tables which are intended for the presentation of data
