Documentation Theming of f:table is unclear/missleading

According f:table documentation page (http://grails-fields-plugin.github.io/grails-fields/snapshot/ref/Tags/table.html), f:table tag accepts 'theme' attribute as other tags.žHowever, it is quite unclear where _table template should be stored(docs mentioning that "When theme is specified, the \_display template will be searched first in theme." which is quite unclear.
Also, I suppose that further clarification of how to use themes for _list templates is also needed.

Start with the f:table documentation page linked in the issue and review its description of the theme attribute, _table templates, and _list templates. Clarify where themed templates are stored and add an example showing how themes apply to each template type; the documentation is done when these lookup paths and usage steps are explicit.
