Hi Gita -
&nsbp; means "non breaking space". In other words, its just a space character " ".
Wiki: http://en.wikipedia.org/wiki/Nbsp
Since Method displays text on a web browser, we sometimes have to do things to appease the web gods. Browsers will automatically trim duplicate spaces, so if you put in text like this " " (5 spaces), the browser would say "oh, they didn't mean that, they meant a single space, and your results is just " " (1 space). But if you do "&nsbp;&nsbp;&nsbp;&nsbp;&nsbp;", the browser says "oh, they really do want 5 spaces after all".
Hope that makes sense. Haven't had my morning coffee yet. :)
