Sort css clases based on th instead of a

[juanpabloprado]

I'm migrating from using tablesorter I've a query would it be possible for the table header to be clickable so it can take a much appropriate space than just the anchor link text, also by making the th responsible of clics we can add something like a border bottom in the th clicked.

Anyhow, thanks for the great thymeleaf dialect and regards.
