title: How to generate a cartesian product of two internal tables?
body: <p>I actually have a simple requirement. 
  There are two tables given:</p>
  
  <p><a href="https://i.stack.imgur.com/GsjiF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/GsjiF.png" alt="enter image description here"></a></p>
  
  <p>What is the most performant way to get a third table with all possible combinations of the values from these tables, starting with the values from the first table? Well like 1A, 1B, 1C, 2A.....etc.</p>
  
  <p>Is there any standard framework I could use for this?</p>
