Extract HTML from Inspect Element

Using HtmlAgilityPack, I use the following code to get the HTML of a website:

var url = "teste.com";
var web = new HtmlWeb();
var doc = web.Load(url);

But the data (a table) I want to extract from the site, only appears in the inspect browser element and not in the source code ... How can I get all the contents of the preview element?
