Is there a way to import a csv file into a (default) page and have it rendered as a table?
The ‘table-importer’ plugin (which is not maintained anymore) does not work on my Grav v1.7.41 site.
If you have a custom Plugin (Custom Plugin tutorial) in your project, you could try to write a function which takes the CSV and converts it to a list of objects which you can use in your twig template (I think there should be one which is used to export flex-objects to CSV Formatter).
I don’t know if you can convert your CSV into a flex-directory and use it in your templates as flex-objects.
I’m not 100% sure, these are just some ideas on how it could be done
