Create table without datasource

I am trying to have a table which gets all info from JSON result returned by controller,
but seems using datasource is a must.

How can I create a table without using entity,
or can entity get info by real-time JSON result?

Thank you.

Hi,

this is possible. Here’s an example that does that: https://github.com/aleksey-stukalov/custom-datasource
