[O] export latex in a table

[zwz]

Hi, I want to export a table to pdf as follows:

* test
| \textcolor{red}{range} | \textcolor{blue}{0\sim2^{8}-1} |

I checked the generated tex.
The first column is OK. While in the second column, the result is something
like:
\textcolor{blue}\{...\}

I don't know what is the right way doing this, but it worked for org-mode <
8.0. 

May somebody help me out?
