Do you need to share small-sih tabular data and have some control over it? Use Github's gists. Unless your data is quite large, it will render CSVs just fine, allow for edits, comments, title, ... And it's in your account, so you can keep track.
I just tested it out and the gist works pretty well! It did confuse me for a minute that it didn’t render the table view on mobile, and there is no way to sort the columns as well.
