\begin{code}
term(\aligncolumn){ent(integer)}{ent(columnspec)}
\end{code}
The |ent(integer)| denotes the number (i.e.~as displayed by the
editor) of a column. Note that @lhs2TeX@ starts counting columns at 1.
As |ent(columnspec)| one can use about the same strings that one
can use to format a column in a @tabular@ environment using the
\LaTeX\ @array@~\cite{array} package. Table~\ref{columnspec} has a short
(and not necessarily complete) overview.
\begin{table}
\centering
\begin{colorsurround}
\begin{tabularx}{\linewidth}{cX}
@l@ & left-align column \\
@c@ & center column \\
@r@ & right-align column \\
|term(p){ent(dimen)}| & make column of fixed width |ent(dimen)| \\
|@@{ent(tex)}| & can be used before or after the letter specifying
alignment to suppress inter-column space and typeset
|ent(tex)| instead; note that this is usually achieved
using just one \texttt{\atsym}, but as @lhs2TeX@
interprets the \texttt{\atsym}, it must be escaped \\
|>{ent(tex)}| & can be used before the letter specifying the alignment
to insert |ent(tex)| directly in front of the entry
of the column \\
|<{ent(tex)}| & can be used after the letter specifying the alignment
to insert |ent(tex)| directly after the entry of the
column
\end{tabularx}
