Vertical table alignment not working with reveal.js backend

[Zlika]

Hi !
The following code is working with the html5 backend, it prints a table with an image and a text, both vertically aligned. However, with the reveal.js backend, the vertical alignment is not honored.

[cols=".^1,.^2"]

The necessary styles are missing. You'd need to copy them into your theme CSS for now.

Here are the styles you need:

This is part of a larger issue that AsciiDoc requires CSS to activate certain features, so we need to include "base CSS" that works with all themes that implements the AsciiDoc-related features such as table alignment. HTML can only describe so much. CSS is needed for some of it.

Related to #23.

Thanks for the workaround!

This is fixed with #288. It will be part of the upcoming 3.0.0 release.
