Sobre esta regra de acessibilidade
For screen reader users to efficiently navigate tables, the scope element must be utilized correctly on tables in accordance with either HTML4 or HTML5 specifications.
If utilized properly, the scope feature greatly simplifies table navigation for screen reader users. When misused, scope can make table navigation far more difficult and ineffective.
The assumption made by a screen reader is that a table has a header that identifies a scope. Having an accurate header makes viewing a table for those who use screen readers far more accessible and effective due to the way the devices work.
