---------------------------
#+caption: ä¸­æ–‡æ ‡é¢˜
#+caption: English Title
| 1 | 2  |

I think this is the best document construct, simple and  intuitive.

But, realizing this feature need some dirty hack, the main reason is
that \bicaption often a custom latex command, fig caption and table
caption are different in option, for example:

\bicaption[图]{...}[fig]{...}
\bicaption{图}{fig}{...}{...}
\bicaption{...}{...}

\bicaption[表]{...}[Table]{}

It is a very useful tip, thanks!
