title: Google spreadsheets function for filtering columns
body: <p>I have a Google Spreadsheet. In Sheet2 I have some data, and in Sheet3 I want to filter the data in Sheet2. Specifically I want that in Sheet3 will be collected only those columns of Sheet2 that contains a specific variable.</p>
  
  <p>See the image above, this is the Sheet2</p>
  
  <p><img src="https://i.stack.imgur.com/dNJvs.jpg" alt="Table1"></p>
  
  <p>I want in the Sheet3 only the columns that contain the keyword "Gaetano" in the row 6.
  So the resulting table will contain ONLY the column B and C of the Sheet2.</p>
  
  <p>I read a lot about the FILTER function, but I cannot still solve my problem.</p>
  
  <p>Thanks in advance.</p>
