Hello Patrick

Thank you for your interest in our plugin.

wpDataTables doesn't yet have any templates that you can use for creating tables, but I assume you were referring to a page/post template, correct?

Creating tables with wpDataTables can only be done by administrators, from the back-end, so your users wouldn't be able to upload a CSV file from the front and create a table like that.

These files can be stored in the database only by importing the file through the table creation wizard, and when you do that, the plugin reads the table and based on its content it assigns column types.

In order for the generated tables to be displayed on a page, or a post, you need to add the table's shortcode. 

The plugin doesn't have any options to limit who's going to see the page, so in order to display the page only to the logged-in users, you'll need to use some membership plugin that will block access to non-logged-in users.

You're welcome, Patrick, I hope that helps you achieve what you need.

Please feel free to reach out to us if you have any further questions.
