title: Find Row Index on DataTable
body: <p>Is it possible to get the row index of a DataTable so that you can access the previous and next row? For example I have a DataTable that contains two columns ChapterTitle and PageURL. This is for a table of contents of a book. ChapterTitle is the chapter name and PageURL is an HTML page that contains the chapter (chaptername.html). When going into one chapter of the book I want to be able to tell which is the next and previous chapter.</p>
  
  <p>After finding the chapter that I'm currently in how can get the next and previous rows?</p>
  
  <pre><code>ChapterTable.Select("PageURL = '" &amp; PageURL&amp; "'")
  </code></pre>
