title: Join two tables row by row
body: <p>I have two tables   </p>
  
  <pre><code> Col1  COl2  COl3  Col4
      1          3     
      3          5      
      4          6     
  </code></pre>
  
  <p>and second table is also the same  </p>
  
  <pre><code>Col11  COl21  COl31  Col41
    1            3     
    3            5      
    4            6 
  </code></pre>
  
  <p>I want to go row by row and produce an output as below</p>
  
  <pre><code>Col11  Col21       COl31  Col41
   1     Col1/Col11    3    Col3/Col31
   3     Col1/Col11    5     ..
   4     Col1/Col11    6     ....
  </code></pre>
  
  <p>I could do an inner join and find matching records but in this case I don't have any column to match to and I just want to go row by row and calculate it.. Can someone please tell me how I can achieve this.</p>
