title: C# datatable decimal with precision
body: <p>I have this code to add new column to datatable:</p>
  
  <pre>
  DataColumn col = new DataColumn("column", typeof(decimal));      
  col.Caption = "Column";
  mytable.Columns.Add(col);
  </pre>
  
  <p>How can I specify decimal precision for this column so the value will always be in the format I want it to be?</p>
