Handle tables with many columns

Boost.URL has this table that's too large and ends up outside the area of the main content:

There should be a solution where we can scroll right or some other option.

Of course, we can also rethink this individual Boost.URL table format. We migrated it from previous QuickBook documentation. But I expect this problem to reoccur with other libraries.
