Hi, Alberto

Sorry for the delay

-

I am sorry, but I am not sure if I fully understood this use-case.

We have various advanced filters available, please check them out here, with explanation with examples how they work.

Could you elaborate a bit more about this use-case?

If you mean to use the table's "global search" to search for multiple columns at same time, we will explain how the logic for that works in our plugin.

The search does look through the entire table, meaning if you have two columns that contain the same search value - both rows will appear:

However, if you were to type "Speakers Blu-Ray Players" it would break, because there's no cell that contains all that. Please feel free to add this as a feature suggestion on this page, so our developers can take it under consideration for one of our future updates.

Let me know if that is perhaps what you need, or if you need something else, please elaborate a bit more;

if you can provide any screenshots of a working example, or a video.

Thank you

And i just wanted to point out that you can try wpDataTables before purchasing

 on our sandbox Demo sites ( you can find links for the main plugin Demo,  

as well as add-on Demos, in my signature),

and there is a 15-day money-back guarantee period, 

so if you purchase the plugin, you can safely fully test it out, and if it doesn't fit your needs you can request and receive a refund in that period. ( same goes for all plugins and add-ons)

Let me know if you have any additional questions.
