crash in table parser

[ckruse]

I just noticed a problem in the table parser. Given the following document:

----|-------------------------------------|
----|-------------------------------------|
----|-------------------------------------|

----|-------------------------------------|

(notice the trailing newline) the kramdown parser breaks as follows:

➜ ckruse@vali ~  % kramdown ./test.md

➜ ckruse@vali ~  % kramdown -v
1.7.0
➜ ckruse@vali ~  %

This happens as well when I use the kramdown parser in a Ruby block.

Thanks for the bug report! I will look into it as soon as I have time.
