body: <p><img src="https://i.stack.imgur.com/dYecy.png" alt="Hide part of the duplicated information"></p>
  
  <p>Please refer to the sample image above, how can I implement that ?  While at the same time change least code ?  </p>
  
  <p>I know I can use isPrintRepeatedValues, but I have two column, while sometimes maybe one column is the same, but the other column is different, so isPrintRepeatedValues seems will not work.</p>
