Github tables are not properly rendered

[MachinesAreUs]

I happens with any table. It's not a marked issue, since I tried the same tables directly with marked.
Tests done with:
elm-markdown
marked 0.3.3

I'd figure out by myself what's going on, but right now I don't know how to use a Elm package without using elm-pagage (i.e. use a package in development mode).

@MachinesAreUs, without a code example of what fails for you, it is difficult to reproduce this issue.

That said, I strongly suspect the cause was an error in the native implementation, which I fix here: #11.
