title: If two values on the same row exist in a table
body: <p>I have a table A</p>
  
  <pre>
  +=========+=========+
  | Column1 | Column2 |
  +=========+=========+
  |    A    |    1    |
  +---------+---------+
  |    A    |    2    |
  +---------+---------+
  |    C    |    3    |
  +---------+---------+
  |    A    |    3    |
  +---------+---------+  
  </pre>
  
  <p>I have another table B</p>
  
  <pre>
  +=========+=========+
  | Column1 | Column2 |
  +=========+=========+
  |    A    |    3    |
  +---------+---------+
  |    A    |    2    |
  +---------+---------+
  |    C    |    6    |
  +---------+---------+
  |    D    |    4    |
  +---------+---------+ 
  </pre>
  
  <p>I want to check for table B, 
  If the values in column 1 AND column 2 are in table A, on the same line return 1. </p>
  
  <p>Obviously I cannot use a Vlookup as I am lokoing for 2 values. Any idea how to complete this?</p>
