I'd like to generate a table with two columns that overlap, since both columns can contain very long content. Something like this:
[width="100%",cols="25%,25%,25%,25%",grid=none]
|====
3+| *Col A* |
| 3+| *Col B*
4+a| '''
3+| This is a very long cell lorem ipsum lorem ipsum |
| 3+| This is also a very long cell ipsum lorem ipsum lorem
|====
However, I don't see how to specify row separators only every other row. Is there any way to do this in table markup? I tried to fake it using a row containing just an asciidoctor horizontal rule, but that doesn't quite work (connect to the table borders), and wastes vertical space.
(No, flowing the column text won't work - in actuality the content is an extremely long C structure.member name and the goal is to have it readable in the table without being broken up).
