Extracting data from web page (table etc); will HtmlDoc be included in LA?

Hi Gintaras，

I am still studying this code.  The line I marked can be replaced by var cell = row.Navigate("ch2") . Why did you use ("fi ne")?  I didn't understand it until I tried using ch2. Could you please explain why you use ”fi ne” ? Any difference between them？

Thank you so much！
