Hello again!

I would like to know the best solution for inserting tables so that they are responsive, keep the information organized (like this one from "Specifications": http://telluspowergreen.com/global/dc-chargers/).

I bought the Responsive Data Table extension but it didn't work right (or I don't know how to use it right...).

Any tips?

You should be able to do something like this with Responsive Data Table extension

If it does not work for you, then this is most likely a configuration issue.
To be able to help you, I need to know exactly what you have done.
