.common-table class?

Created by: tonymalatanos

In docs/index.html, each code snippet for tables has the class common-table on the <table> tag, yet the real markup does not have this class. It's also nowhere to be found in the CSS/LESS. The <table> tag itself is styled rather than the common-table class. Can I get some clarification on this?

More broadly, is having a default styling of the <table> tag and resetting when (if?) necessary better than having a class for your "default" table style? That's something I wrestle with.
