Greetings from a first-time contributor. Another patch contributor, Uwe Brauer, recruited me after finding some code I had written to move single org-table cells up/down/left/right. I found this feature to be useful in certain kinds of tables so wrote the functions for myself but am told that others might benefit from it.I have formalized that code into a git repo with a feature branch on it which may be found here:I have included documentation in org-table.el for the new functions and tests for them. If further work or documentation needs to be done, please let me know. I am also not sure if I got the commit messages formatted to the specification mentioned on the contributing page. I am happy to explain more if needed.I just mailed assign@gnu.org to get the copyright for the code resolved but thought I would put up this branch now so others can have a look.Cheers,Chris
