问题 I am working on an ASP.NET MVC project which converts a view to a PDF. Previously, Rotavia was used, but then a new client requirement is that the PDF be accessible/508-compliant. For layout purposes, the previous developer had a whole header section (logo, title, disclaimer, etc) as a table without th elements (just td).
