title: Why does the returned DataTable has readonly columns in FileHelpers
body: <p>I am wondering why <a href="http://filehelpers.com/runtime_classes.html" rel="nofollow noreferrer">filehelpers</a> return readonly columns.</p>
  
  <p>I had a huge problem with <a href="https://stackoverflow.com/questions/9219717/why-does-the-value-not-get-updated-in-my-datatable-row">them </a> not updating values and could not figure out why. Now I have to have another loop to go through all the columns and change them to be not readonly.</p>
  
  <p>Is there a way I can tell Filehelpers to not do this? So I don't have to waste time going through all of it again?</p>
