WCAG 1.3.1 Info and Relationships Level A
Who this affects
A table header describes no cells, which usually means the table is used for layout.
How to fix it
If the table presents data, connect headers to cells with scope or headers. If it is layout, use CSS instead.
How much work is it?
Usually a template or design change. That is a rough guide for planning, not an estimate for your codebase. A single content edit repeated across a template is a template change.
What a person still has to check
Passing this rule does not mean 1.3.1 passes. Automation checks part of the criterion, and the rest is a judgement:
Confirm headings, lists, and tables are marked up as such, and that visual grouping is reflected in the markup.
