title: Extract column from table with empty and non empty columns with awk
body: <p>I have a table with some server details and I need to extract their status</p>
  
  <pre><code>Server            Server-ID        Hostname         Last Online               Status        
  ------------     -----------       ---------        --------------            ------
  server1                                             2018-Mar-13 21:39:45      RUNNING
  server2                                             2018-Mar-13 21:39:35      RUNNING
  server3                                             2018-Mar-13 21:51:32      RUNNING
  server4          XX-YY             ubuntu           2018-Mar-13 21:55:04      RUNNING
  server5                                             2018-Mar-13 21:52:48      RUNNING
  server6                                             2018-Mar-13 21:43:58      RUNNING  
  </code></pre>
  
  <p>Output required:</p>
  
  <pre><code>RUNNING
  RUNNING
  RUNNING
  RUNNING
  RUNNING
  RUNNING
  </code></pre>
  
  <p>From the above table I need to get the Status of all the servers. The columns Server-ID and Hostname can be empty or have a couple of entries. What is the simplest way I can do this?
  I tried a couple of awk commands but didnt find a complete solution</p>
