Hi @nationwidestudios,
We added a new feature to WP Data Access to support POST requests for search forms. The new feature will be available with the next update which is planned to be released next week. It works just like GET requests. You just need to change your form method.
>>> we also want to hide the everything on the table except for the results of the search
You can do this in the arrange section of the Extension Manager. This is documented here:
https://wpdataaccess.com/docs/data-tables/extension-manager/
>>> Would it be possible to pass the search criteria to a custom query on the tables page instead of loading the table?
A good way to handle this is to create a database view for you custom query and then create a Data Table from your database view just like you would with a database table.
Hope this helps. Feel free to create a new thread if you have other questions.
Since you have a premium license you can also ask for premium support here:

We’re glad to help! ??
Best regards,
