ENH: Issue #2679. DataFrame.to_html() to create hyperlinks for valid URL...
Closes #2679 

how does this handle the automatic HTML pretty-printing of dataframes in the ipython notebook? is the presentation of URLs affected?
 Aa far as I know it shouldn't. All it does is check for a valid url string and then put the value in an 
<a> tag.
 would you mind doing a quick sanity check of the notebook output under your patch? e.g., this is what I currently see:

 For what it's worth, I don't think it would be a bad thing for the notebook output to include URLs as links, but it would definitely be annoying if they are pretty-printed as a HTML code inside the table :).
 this should to be optional at the very least if not off by default for backward compatibility.
`to_html` is not used solely for ipnb display.
 @tdas14 this needs to be an option when printing (e.g. passed to `.to_html`).
 @tdas14 this needs to be an option directly to `.to_html`, further, you could add a global option in `display.html.render_links`, as a boolean (default should be False for back-compat)
 closing, but if you would like to continue working on this pls reopen
