Subject: [PATCH] Allow wrapping for ARM table content

RTD style default never wraps <th> and <td> elements and that just does
not work for real sentences or any other long lines.

We can reconsider styling some tables separately, but at the moment we
do not have use for tables with long but unwrappable lines so it's
easier to allow wrapping globally.

(cherry picked from commit a5dd98ac1bde58a79b105ed44952628525c27f6b)
