Hi!
It very much depends on how the tables are stored and printed. If they are within the content as shortcodes, then using the index table engine will very likely do the trick. Make sure to configure and enable it as described.
In case the shortcodes are within the post excerpt (short product description), then it might not be possible to get their content. There might be a solution, but it involves adding a custom code to executed excerpt shortcodes as well.
1. Make sure to have a full site back-up before making any changes in your site files!
2. Place this into the functions.php file in your active theme directory (copy from line 3 only!):
3. Make sure to re-create the index table after that.
If you need any help with this, you can leave FTP details and I will try to implement it for you. Please note that I cannot guarantee this will work, but it’s worth a try.
