Hi,
with “myPHP”, do you mean “phpMyAdmin”, the tool to manage mySQL database tables? If so, there was a misunderstanding, I’m afraid. TablePress 2.0 will not support direct use of mySQL tables! It will also not support “cross-queries” (or “JOIN”s, if that’s what you mean! TablePress will continue to use its own TablePress table format.
It will however be easier to work with large tables on your site (e.g. imported from a CSV file), as the “Edit” screen should not be freezing anymore (this is something that you can already test with the current test version of TablePress 2.0 from my link above).
In addition, the new Server-side Processing Premium feature will make showing large tables on the frontend much faster. Where without this feature (i.e. also previously), the full table data had to be downloaded by the visitor, with that feature only the needed rows will be loaded.
The pricing of this feature (it will be just one of multiple new features) is not yet fully decided, as I’m currently looking into creating different premium plans.
As for “visual differences”: You should be seeing a new “Edit” and “Import” screen, as these are independent of the Classic Editor. You will then however indeed not be seeing the new “TablePress table” for the Block Editor, which I think also is a nice feature, as it makes embedding tables easier (no more need to deal with Shortcodes). Of course, Shortcodes will continue to work and will still be supported in the future (they are the internal foundation of the block, actually)! So, nothing to worry about there ??
Regards,
Tobias
