title: Remove columns from DataTable in C#
body: <p>I have a DataSet which I get a DataTable from that I am being passed back from a function call. It has 15-20 columns, however I only want 10 columns of the data.</p>
  
  <p>Is there a way to remove those columns that I don't want, copy the DataTable to another that has only the columns defined that I want or is it just better to iterate the collection and just use the columns I need.</p>
  
  <p>I need to write the values out to a fixed length data file.</p>
