Most Markdown parsers don't support tables without headers. That means the separation line for headers is mandatory.

Parsers that do not support tables without headers

• multimarkdown
• Maruku: A popular implementation in Ruby

• PHP Markdown Extra "second line contains a mandatory separator line between the headers and the content"

• RDiscount Uses PHP Markdown Extra syntax.
