Implications

Users with low vision who zoom content may not be able to make sense of the table or understand its content.

Expected outcome

Ensure that text can be resized to 200% without any loss of content or functionality.
For data tables, it is acceptable for a horizontal scrollbar to be present and required for viewing the table content.

1.4.4 Resize Text WCAG 2.0 Level AA Except for captions and images of text, text can be resized without assistive technology up to 200% without loss of content or functionality.

Many users with mild visual disabilities need to enlarge the text size on web pages. Since all recent versions of the most popular web browsers offer the option to zoom in content, it is important to ensure that pages scale effectively when users utilise this feature.
