Graphics, Figures & Tables ⇒ problem: tabular with nested environment

[daroepi]

I have a table with two columns inside which I want to use a custom environment called "mgroup". This environment is defined as follows:

Code: Select all

\newenvironment{mgroup}[1]{#1 &}{\tabularnewline}

An example of how I use it:

Code: Select all

\begin{tabular}{ll}%
\begin{mgroup}{g1}%
one%
\end{mgroup}%
\begin{mgroup}{g2}%
two%
\end{mgroup}%
\end{tabular}

The example does not compile successfully. When I remove the ampersand and tabularnewline it does compile but everything is output on the same row (as expected). The mere use of a nested environment (that uses align and/or newline) seems to cause a problem within tabular.

Can anyone fix the above? Or, can anyone offer another way to accomplish the above? Note, I need to use a nested enviroment of some sort because I may need to process the input arguments in future.

Hi,

would a command (instead of an environment) be a viable option for you?

Code: Select all

\documentclass{article}

\newcommand\mgroup[2]{#1 & #2\tabularnewline}

\begin{document}

\begin{tabular}{ll}%
\mgroup{g1}{one}
\mgroup{g2}{two}
\end{tabular}

\end{document}

Thank you kindly for your reply. Though I still hope someone can fix my environments {intellectual itch}, I am grateful to have an alternative solution to my problem.
