title: axlsx: conditional formating with multiple rules, with one condition applying to another column
body: <p>I would like to develop a conditional formatting in axlsx with at least one rule applying to another column.
  I.e. I have text in column A (e.g. "A", "B", "C") and data in column B (e.g. "1", "2", "3"). Is it possible to build a condition </p>
  
  <pre><code>IF colA = "B" AND colB &gt;= 2 THEN APPLY conditional formatting to colB
  </code></pre>
  
  <p>within the frame of axlsx?
  I hope, my pseudo code makes my intention clear.
  Best regards, and thank you in advance!</p>
