Yeah, but what if the document contains multiple tables, and you want 
explicitely the one with the class 'dataTable tm10'?

In such a case it doesn't hurt to progressively narrow down on the 
wanted element.

It also makes the scrape code more robust against page changes. Someone 
could add an extra table to the start of the page to host a search box, 
for example.
