如何在 pdfLaTeX 中编写此内容?我们必须使用 align

我必须在学校作业中写一份数学符号列表,例如 N、R、并号、不等于号和其他一些符号。我知道所有命令,但如何将它们放入我的文件中,并在它们之间留出空格并居中,而不会收到错误消息?

只是初学者

听起来你正在做类似的事情综合 LATEX 符号列表.如果你看看来源对于该文件,他们的表格格式如下(Negated Harpoons第 81 页的表格复制到此处):

\begin{symtable}[MNS]{\MNS\ Negated Harpoons}
\index{harpoons}
\index{restrictions}
\label{mns-nharpoons}
\begin{tabular}{*3{ll}}
\K[\MNSndownharpoonccw]\ndownharpoonccw$^*$             & \K[\MNSnneswharpoons]\nneswharpoons           & \K[\MNSnseharpooncw]\nseharpooncw                       \\
\K[\MNSndownharpooncw]\ndownharpooncw$^*$               & \K[\MNSnneswharpoonsenw]\nneswharpoonsenw     & \K[\MNSnsenwharpoons]\nsenwharpoons                     \\
\K[\MNSndownupharpoons]\ndownupharpoons                 & \K[\MNSnnwharpoonccw]\nnwharpoonccw           & \K[\MNSnswharpoonccw]\nswharpoonccw                     \\

\K[\MNSnleftrightharpoons]\nleftrightharpoons           & \K[\MNSnnwseharpoonswne]\nnwseharpoonswne     & \K[\MNSnupdownharpoonrightleft]\nupdownharpoonrightleft \\

\K[\MNSnneharpoonccw]\nneharpoonccw                     & \K[\MNSnrightharpooncw]\nrightharpooncw$^*$   & \K[\MNSnupharpoonccw]\nupharpoonccw$^*$                 \\

\end{tabular}

\bigskip

\begin{tablenote}[*]
  Where marked, the ``\verb|ccw|'' suffix can be replaced with
  ``\verb|up|'' and the ``\verb|cw|'' suffix can be replaced with
  ``\verb|down|''.  (In addition, \cmdI[\MNSnupharpooncw]{\nupharpooncw}
  can be written as \cmdI[\MNSnupharpooncw]{\nrestriction}.)
\end{tablenote}
\end{symtable}

如果直接复制它,它将无法编译(它们定义了一些自定义的东西),但它应该给您一个良好的构建点。
