For instance, I can't use Tab to go to next line. It turns out the result of org-at-table-p is nil. I deleted all my configurations, but it doesn't get recognized as well. I'm quite new to emacs, and I can't figure out why. Any instructions on solving the problem or how to debug is appreciated. Thanks for your assistance!
