mkdocs2pandoc exits with error "ValueError: invalid width 0 (must be > 0)" #13

I'm on Ubuntu 15.04 with Python 2.7.10, mkdocs 0.15.3 and using a slightly modified mkdocs-material theme.

When I run the tool, it exits with this error:

Traceback (most recent call last):

ValueError: invalid width 0 (must be > 0)

Any ideas?

First shot (not much time right now): it may be something I have introduced with the fix for https://github.com/jgrassler/mkdocs-pandoc/issues/11. If you like you can try it with mkdocs-pandoc 0.2.5 (git revision 0a0c6b2a6548e169dd4b93cf3ac9503097dca4b6) Can you share your documentation, or failing that, a minimum example to reproduce the problem? If it helps with building the minimum example: the problem occurs in one of your tables (I can tell as much from the backtrace).

I did exclusion principle testing and found that it was some malformatted tables. The content originally came from DokuWiki and was converted using a converter script that produced "broken" tables.

The ones breaking the tool looked like this:

 | IAM Node                                                | Database Node | Engine Node |
 | ----------                                                | --------------- | ------------- |
 | RAM|8GB or higher|32GB or higher|16GB or higher|         
 | CPUs/cores|2 or higher|4 or higher|4 or higher|          
 | Hard Disk|50GB or higher|200GB* or higher|50GB or higher|

As you can see with some major whitespace. I removed that everything works fine for now. Will do more testing. Thanks.
