st: Error arising using '&' in the cells option of -esttab-

[Jamie Fagg <j.fagg@ich.ucl.ac.uk>]

Dear Statalist,

First, Happy New Year. Secondly, I would appreciate advice about the 
following. I am running Stata SE 11.1 on Windows (32 bit).  I am trying 
to use -esttab- (user written - by Ben Jann) to produce a table using 
the following code.
I have run the esttab command previously with Stata 10.1 using the code 
in snippet 1,  and I'm sure that it worked. Specifically, I used an  "&" 
symbol in the cells option to put the relative risk ratios and 
conflidence intervals in the same cell in the table in my rtf file. It 
was nice because it automatically put the RRR and CIs next to each 
other, rather than displayed vertically.
Since I've started using Stata 11.1, I have started getting the error 
seen at the bottom of snippet 1.
Extra details:
The command works when I remove the '&'
My do file uses the 'version 10.1' command at the start of the do file. 
The error remains without this code.
I have checked that the installation of esttab is fully up to date as is 
the rest of Stata
I would appreciate any insights - ideally about whether I can get the 
command running as it did, or how to achieve the same results in the table.
Thanks for your consideration,

Jamie
