Signature field with centred content underneath it

Question

I am using

\documentclass[a4paper,12pt,openany,leqno,footinclude=true]{memoir}

and want some signature lines that have

1. dotted lines; plus

2. a designation below the line

I have:

\noindent\begin{tabular}{ll}
\makebox[2.5in]{\hrulefill} & \makebox[2.5in]{\hrulefill}\\
Ronaldo & Date\\[8ex]% adds space between the two sets of signatures
\makebox[2.5in]{\hrulefill} & \makebox[2.5in]{\hrulefill}\\
Dr. Fernando Torres \begin{center}Assistant Professor Discipline Of Computer Science School Of Engineering La Liga \end{center} \newline  & Date\\
\end{tabular} 

The content of "Assistant Professor ..." does not left align below the signature line and I can't use a \newline too.

I want that content to either be

1. left aligned; or

2. centre aligned (I tried using the center environment, but it didn't work).

I guess centre aligned designation below the signature line would be great.

Here is a minimal example:

\documentclass{article}

\begin{document}

\noindent\begin{tabular}{ll}
\makebox[2.5in]{\hrulefill} & \makebox[2.5in]{\hrulefill}\\
User Representative & Date\\[8ex]% adds space between the two sets of signatures
\makebox[2.5in]{\hrulefill} & \makebox[2.5in]{\hrulefill}\\
Program Manager & Date\\
\end{tabular}

\end{document}

Answer 1

The following should provide you with what you need:

\documentclass{article}

\begin{document}

\noindent
\begin{tabular}{@{}p{2.5in}p{2.5in}@{}}
  \dotfill & \dotfill \\
  Some name & Date \\[5\bigskipamount]
  \hrulefill & \hrulefill \\
  Some other name & Date \\
  \centering
  Some lengthy designation that makes the above-mentioned person feel 
  special to everyone who reads this
\end{tabular}

\end{document}

The key here is to use a p{<len>} style column, as it allows you to perform regular paragraph-like settings (horizontal alignment), including \centering to centre the content.

Answer 2

You have several possibilities to do what you want. Because I'm not sure if centering is always the best I will show you two other possibilities for the layout. One is using the usual block (please see the hyphenation!), one is to use \raggedright, that means left justified text and all centered.

The code (with your used class memoir):

\documentclass[a4paper,12pt,openany,leqno,footinclude=true]{memoir}

\begin{document}

\noindent\begin{tabular}{@{}p{2.5in}p{2.5in}@{}}
\dotfill                         & \dotfill\\
Dr. Fernando Torres              & Date\\
(Assistant Professor Discipline Of Computer Science School Of Engineering La Liga)  
                                 & \\[8ex]
\dotfill                         & \dotfill\\
Dr. Fernando Torres              & Date\\
\raggedright (Assistant Professor Discipline Of Computer Science School Of Engineering La Liga)  
                                 & \\[8ex]
\end{tabular} 

\noindent\begin{tabular}{@{}>{\centering}p{2.5in}>{\centering}p{2.5in}@{}}
\dotfill                         & \dotfill \tabularnewline
Dr. Fernando Torres              &  Date \tabularnewline
(Assistant Professor Discipline Of Computer Science School Of Engineering La Liga)  
                                 &  \tabularnewline
\end{tabular} 

\end{document}

And the result:

Please see that I used \tabularnewline for the last table because the different layout with \centering). To get a centered column I used >{\centering} before p{2.5in}, because p{2.5in} will create a right-left justified column and you need a centered one.
