Hello Cryonic, I'm sorry to hear that this add-on isn't functioning
properly on your tables. To troubleshoot, could you please confirm
if it doesn't work on any table in general or specifically on
certain ones? Since, I personally use this add-on without issues, an
outdated Firefox version might be a possible cause?. It's also worth
mentioning that some websites with complex table structures may not
support this add-on. If you can provide me with the URL of the
website where it isn't working, I could investigate further to help
resolve this issue. Thanks.
