Hello!

The problem I am trying to solve:

1. I have two columns in a table that I need to be editable.

2. The source table/data is DIFFERENT for each column.

Example:

Column1 => table1.column1

Column2 => table2.column2

It's easy enough to make one column editable. Making the second one editable is the challenge.

-----------------

What is the best way to solve this problem?

--------------------

1. I have researched the available actions and filters:
   1. wpdatatables_after_frontent_edit_row: this happens after a save, but i would never get there because of the error that would be thrown on the save itself.
   2. The filters i looked at were: wpdatatables_query_before_save_frontend, wpdatatables_filter_formdata_before_save. The latter one i could try to use, but i believe the intent is to modify data prior to a save - NOT perform additional saves inside this function. And again, I would still have an issue with the save action failing.
2. It almost seems like what i want to do is conditionally override the save table action (wp_ajax_wdt_save_table_frontend) in the plugin - but this is complicated, and very close to hacking the core source code. I'd like to avoid that.
3. I am also looking into Gravity Forms integration. But I'm unfamiliar with GravityForms, and not sure it can do what i want.

Hopefully, I was able to explain the issue. Any help would be greatly appreciated. Thanks!
