Hi, Preeti Rawat.

Absolutely.

All our licence plans have all the features.

The differences between licences is if they are annual/subscription based, or Lifetime,

and the number of domains you will get to be activated at the same time.

-

1. In regards to annual licences, here is how they work :

Every subscription-based license is set to renew every year, on the date of purchase, unless you unsubscribe through the store. 

If you unsubscribe, you will not be charged on the next renewal date, and after that date passes, you will still be able to use the plugin (the version you updated to last before the subscription expired), 

but you won't be able to receive new updates, and you won't have access to premium support.

2. In regards to the Domains on the licence plans :

Basic ( 1 domain) , Pro ( 3 domains) and Developer ( unlimited domains);

and all licence tiers have an unlimited number of subdomains/sub sites,

so if you have a Staging/Test site as subdomain, you can activate as many as needed.

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.
