I'm using the bussproofs package to write some inference rules, but i'd like to horizontally align them. I tried to write them within a two-columned table (one rule in the left cell and the other in the right), but it doesn't work. Any suggestions, please?

Code producing the error, below:

\AxiomC{$\Gamma, A \vdash B$}
\UnaryInfC{$\Gamma \vdash A\Rightarrow B$}
\end{prooftree}} & {} \\

The second inference rule is missing from the code.

    It would be great if you could provide a minimal working example (MWE) that replicates your "doesn't work" instance.

  • I'm using Gummi. It doesn't produce the pdf and the Build Log tab is just blank. So i don't know which is the error. But If it is of any help, I will add the code producing the error.

In the end, I used the mathpartir package and I made it.

\inferrule*[Right=\selectlanguage{english}\emph{Id}\selectlanguage{greek}]{{}}{\Gamma, A \dashv A}
\inferrule*[Right=$\bot_\mathcal{E}$]{\Gamma \vdash \bot}{\Gamma \vdash A}
  • It would be helpful for anyone else wondering about this, or a similar problem, if you explained just how you solved it, perhaps including a minimal code example. Nov 12, 2013 at 13:13
  • ok, just did :)
