I personally dislike the bold header row in Version 1.0 (415).
Bear shouldn’t assume that every table will use a header row. Some tables use a header column instead. For example, see the “Important Links” table in the Panda welcome document.
Also, this header row style is inconsistent with markdown syntax where bold items are surrounded by **asterisks**. See this related thread where you all decided to remove the strikethrough for the checkbox style.
