The new Formats now clarifies that unreleated columns are NOT a table, but lists that happen to be printed next to each other. That is a visual arrangement, nothing more. Formatting should reflect what something actually IS, not necessary just what it LOOKS LIKE. Unrelated columns may be printed to look like tables, but in fact they aren't, and now that issue is simplied and clarified and lists that happen to be printed next to each other are brailled according to what they ARE, which is lists.
