Donald,

Yes, I'm doing this in LaTeX; $and$ denote a change to the displaymath environment.

I was using the to switch back to text mode because the \halign got mangled without it. I realize now that I was missing a closing angle bracket somewhere :): As I understand it, the solution works because \vcenter atomizes its contents as part of the current math list. This solution works quite well, thank you. ---------------------- Abraham Becker Contractor PubMed Central > -----Original Message----- > From: Donald Arseneau [mailto:asnd at triumf.ca] > Sent: Thursday, February 18, 2010 4:16 PM > To: texhax at tug.org; hh-brasil at bol.com.br > Subject: Re: [texhax] Stretch Brackets Around\halign> > "Becker, Abraham (NIH/NLM/NCBI) [C]" <beckera at ncbi.nlm.nih.gov> writes: > > > I'm trying to stretch some brackets around an \halign table which is > in text mode, but having some difficulty, as the brackets are > disappearing. > > > > Could you please offer a suggestion on how I can improve this? > > > > \[ > > \left[ > > {\offinterlineskip\tabskip=0pt
