title: Datatable -filter records with linq based on some internal index
body: <p>I have a datatable with plenty of records. And i have a range like <strong>lowerRange = 10</strong> and <strong>upperRange = 200</strong>. <strong><em>I want the pull the records starting at row 10 till row 200.</em></strong></p>
  
  <p>Now <strong>i don't want to add any new index based column</strong> into the datatable. Is there any way with the help of linq, i can pull the set of rows based on some internal datatable index? I guess, the datatable must be maintaining some row index implicitly.</p>
  
  <p>Please suggest.</p>
