title: loop through datatable using column name but not exact column name
body: <p>I am trying to get cell values of particular column having Column name which is not fixed after particular words.
  i need to loop through Datatable and get values from column having column name as something like 'Value @02/29/2019'.
  Here Date is changing but i want to know whether we can have something like contains or 'Values%'.</p>
