Hi,
This may be a bit of an edge case, but it's not too rare.
I tested DiscussionTools' reply button on my user talk page in the Arabic Wikipedia. I did it in a section in which a bot posted a greeting for 600,000 Arabic Wikipedia articles. This greeting was formatted as a table.
The Reply button itself appeared inside a table, which was already not quite right. When I posted the reply, it was posted inside a table, too. This is not what I would want, at least not in this case.
