Every time I read a plugin, theme or theme component description, which is presented in a table, it annoys me. Because I have to scroll horizontally to read the whole description, I often trigger the table builder edit option. Then the text is a lot more difficult to read because the contrast is bad.
This is a topic where I cannot even use the table editor because I am not allowed to edit the post. Those are the most confusing ones because the edit button does not appear, and you have no indicator of why the contrast changed. When I am allowed to edit the topic because it is a wiki, the pencil button that helps to know what happened covers parts of the text.
Opening a footnote in a table also results in a lack of contrast, so you have to find a place to tap afterwards.
And as @Canapin mentioned, in bigger tables like Trust Level Permissions Table (inc Moderator Roles) clicking somewhere else is not really possible.
But even in my first example, it is not easy to find a place next to the table.
All in all, it is annoying to always have to look for a place to touch to continue reading. And at least for topics where I am not allowed to edit, I don’t understand why that happens at all.
