Finally discovered what was breaking my markdown tables, orgtbl-mode was hijacking TAB and changing the pipe character in the table into a plus character. I've https://github.com/clojure-emacs/cider/issues/3125`cider-clojure-cli-aliases`https://github.com/clojure-emacs/cider/issues/3125 which is usually done in a .dir-locals.el file. Basically removing all the execution options and fixing the double colon that is sometimes produced in the jack-in command Also fixed some links in practicalli/clojure-deps-edn and streamlined markdown rules I'm using via MegaLinter (a GitHub action I'm steadily adding to all the books to enhance the quality)
