1 Initial Problem

Screenreaders get dizzy by some tables in notification mails. While it is technically possible "to get" the content, it is unneccessarily hard.

Because knowing and memorizing the structure of a table can be important for orientation in a document, each step, while navigating through the nested table rows and cells, is read by the screen reader.
