After a quick look, I do have some major concerns:

• have you compared your formatting with the rest of my code?
• using line.next.next without checking if line.next is != null is a bad idea
• refrain from using regex (you may have noticed that I do not use a single one), and even when I allowed regex's, they should be compiled
• <tableHead> isn't even valid HTML
• a table is not standard markdown, so it should not be parsed when not in extended mode
• don't document new Markdown features with code comments, if it's a new feature it belongs into README.md, basically all of your comments (except the JavaDoc ones) can be removed

Thanks for your reply,and something I want to know:

• did you means that all code committed need the same formatting?I found the different between your code and mine before I committed.
• this place I can make sure that line.next is not null,so I am not check it
• I want know why you not use regex in your code?because of performance or other?
• did you means all not standard markdown could not in this place, and need add in any other place?
