\par{The next chart should have normal column formatting in the image of
this document typeset with \LaTeX{}. \   The purpose of this demonstration
is to make the point that \emph{latexcommand} should be allowed inside
containers such as \emph{display} and \emph{footnote}. \   (Otherwise, if
the \emph{latexcommand} used in this document for \emph{tabular}
column tightening is placed ``loose'' in the document,
it affects all subsequent instances of the chart.)
