I don’t think tables are a common requirement for a user forum, Shiki, and we won’t be making any future forum choices on the basis of that requirement. You can always post a link to a Google spreadsheet, or an Excel file, or any number of other things. And if you want to be helpful and provide feedback to us in the most useful fashion, doing so with a separate document that we can easily pass on to our translators is way, way more useful than embedding a table in a forum post in any case.
