title: Azure Table Storage: a script to populate new column for existing tables
body: <p>I have some tables in my Azure Table Storage and need to deploy a script to populate a new column with empty data for all of them.</p>
  
  <p>I know that some management could be done via PowerShell, but I was unable to find any relevant example or documentation on how to perform this task.</p>
  
  <p>Any help would be appreciated.</p>
