I'm trying to define a shortcut using \newcommand for setting up a table using the tabularx environment. The command seems to work fine when beginning the table:


But doesn't work when ending the table:


The error message that I receive is:

! Missing } inserted.

<inserted text> 


l.33 \end{tabularx}
  • Hi Richard, welcome to TeX.sx! I've formatted the code in your question. You can also do that yourself by selecting the code segments and clicking the {} button. Also, it's generally a good idea to include a minimal working example (MWE), i.e. the smallest complete, compilable document that demonstrates the problem.

    The tabularx environment only looks like an environment, but it's actually a command. See How to include tabularx/y in a new environment.

An environment \begin{tabularx} expands to \begingroup\tabularx and \end{tabularx} expands to \endtabularx\endgroup.

With \let\a\b you can 'copy' the definition of macro \b to \a. That's how you create the short name:


Note: This does not copy the group.


 foo & bar
