# Aliasing a variable argument command into tabular environment [closed]

I am making a multi-language document. With the big help of Mr. Steven B. Segletes, I am able to deal with several languages mixed document, which can only output in wanted one or several laguages. See the thread [ Parse command argument separated by comma ]

I also aliased \mulan to new commands such as \mulanp and \mulanr so that the \mulan command can be simplified when the text is seperated by \par or '/'.

Now I want it can also works in table use. I know I can not insert a multiline sentence in a tab cell. So I hope the contents explained by \mulan command can be treated as a sub-tabular. Just like the following,

\mulanTL{A}{B}{C}


will give output

\begin{tabular}{l}
A \\
B \\
C\\
\end{tabular}


I don't know how to define it. I tried a lot bu failed. The following is my minimal example. Though I am not sure you can compile it correctly because it includes CJK characters.

If the number of arguments is fixed to, e.g. 3. I can make the command as follows,

\newcommand\mulanT[4][l]{
\begin{tabular}{#1}
\mulan{\\}{#2}{#3}{#4}
\end{tabular}
}

\newcommand\mulanTL{\mulanT[l]}
\newcommand\mulanTC{\mulanT[c]}
\newcommand\mulanTR{\mulanT[r]}


Is there any means to deal with the case with variable number of arguments? if it requires the editing of the definiton of command \mulan, that will also be O.K. Thanks in advance.

• So are the number of arguments to \mulanTL variable? Or will it always be 3? – Werner Feb 13 '15 at 1:46
• The number of arguments to \mulan varies. It is better if you define \mulanTL with a variable number aguments too. If it is impossible to define that, you can fixed it as three. – Jilong Yin Feb 13 '15 at 2:07
• Is there anybody help me more? – Jilong Yin Feb 15 '15 at 12:28
• @Werner please see Jilong's comment above. Jilong, please use @-notation (as I've done here for Werner) to notify them of your reply to a comment. – Paul Gessler Mar 15 '15 at 2:20
• If it is a variable number of arguments, what syntax do you want to use? One needs some way to know that there are no more arguments to process. – Andrew Swann Jun 13 '15 at 19:00
