I have produced the following table with LateX, using the multirow and array packages. The final result is:

Transportation problem table

However, I noticed that the labels L1 and L2 are not quite vertically aligned with the entries $a_{11},a_{12}$, etc. Why is that? Is there anything wrong with my code (which has some code which was copied and pasted from other answers)?

\documentclass{article}
\usepackage{multirow}
\usepackage{array} 
\newcommand{\nocorner}{1cm}
\newcommand{\corner}{6mm}

\newcolumntype{L}[1]{>{\raggedright\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}
\newcolumntype{C}[1]{>{\centering\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}
\newcolumntype{R}[1]{>{\raggedleft\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}

\begin{document}

\begin{table}
    \setlength\extrarowheight{3pt}
    \begin{tabular}
        [c]{c C{\nocorner} C{\corner} C{\nocorner} C{\corner} C{\nocorner} C{\corner}}
         & \multicolumn{2}{c}{$H1$} & \multicolumn{2}{c}{$H2$} & \multicolumn{2}{c}{$H3$}\\\cline{2-7}
        \multicolumn{1}{c|}{\multirow{2}{*}{$L1$}} &
         \multicolumn{1}{C{\nocorner}}{\multirow{2}{*}{$a_{11}$}} & \multicolumn{1}{|C{\corner}|}{$c_{11}$} & \multicolumn{1}{C{\nocorner}}{\multirow{2}{*}{$a_{12}$}} & \multicolumn{1}{|C{\corner}|}{$c_{12}$} & \multicolumn{1}{C{\nocorner}}{\multirow{2}{*}{$a_{13}$}} & \multicolumn{1}{|C{\corner}|}{$c_{13}$} \\\cline{3-3}\cline{5-5}\cline{7-7}
         \multicolumn{1}{l|}{} & \multicolumn{1}{C{\nocorner}}{} & \multicolumn{1}{C{\corner}|}{} & \multicolumn{1}{C{\nocorner}}{} & \multicolumn{1}{C{\corner}|}{} & \multicolumn{1}{C{\nocorner}}{} & \multicolumn{1}{C{\corner}|}{} \\\cline{2-7}
         \multicolumn{1}{c|}{\multirow{2}{*}{$L2$}} &
         \multicolumn{1}{C{\nocorner}}{\multirow{2}{*}{$a_{21}$}} & \multicolumn{1}{|C{\corner}|}{$c_{21}$} & \multicolumn{1}{C{\nocorner}}{\multirow{2}{*}{$a_{22}$}} & \multicolumn{1}{|C{\corner}|}{$c_{22}$} & \multicolumn{1}{C{\nocorner}}{\multirow{2}{*}{$a_{23}$}} & \multicolumn{1}{|C{\corner}|}{$c_{23}$} \\\cline{3-3}\cline{5-5}\cline{7-7}

    \end{tabular}
    \setlength\extrarowheight{0pt}
\end{table}

  • Could you please make a compilable MWE that allows others to reproduce teh output you show? If I add a documentclass as well as the relevat packages to your code, I get the desired alignment.

  • @leandriis: I just edited the code. This MWE produces the problematic output.

    Thanks for editing your question. If I compile your example on my computer, I get the following output: i.stack.imgur.com/QQulu.png that seems quite well aligned to me and differs from the screenshot you showed.

  • @leandriis: This is strange... Maybe I should update my LaTeX system? I'm using TeXLive 2016 (usually I don't update often, since LaTeX is already quite stable).

    There have been major changes in the array package, you should definitely update.

  • With your MWE and using recent version of array package I cant reproduce in question showed image of table. The baselines of "L1" , "a1" and \clines below "c" cells are vertically aligned. Do you have recent version of LaTeX installation? Read comments below question
  • Your code can be much shorter (the most of \multicolumns{1}{...}{...} are superfluous, adding few of \multicolumns{2}{c}{}` simplify a code):
\documentclass{article}
\usepackage{multirow}
\usepackage{array}
\newcommand{\nocorner}{1cm}
\newcommand{\corner}{6mm}
\newcommand\mcc{\multicolumn{2}{c|}{}}  % new

\newcolumntype{L}[1]{>{\raggedright\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}
\newcolumntype{C}[1]{>{\centering\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}
\newcolumntype{R}[1]{>{\raggedleft\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}

\begin{document}

\begin{table}
    \setlength\extrarowheight{3pt}
    \begin{tabular}{c | *{3}{C{\nocorner}|C{\corner}|} }
    \multicolumn{1}{c}{}
         & \multicolumn{2}{c}{$H1$} & \multicolumn{2}{c}{$H2$} & \multicolumn{2}{c}{$H3$}   \\ \cline{2-7}
    \multirow{2}{*}{$L1$}
        & \multirow{2}{*}{$a_{11}$}
            & $c_{11}$
                & \multirow{2}{*}{$a_{12}$} 
                    & $c_{12}$
                        & \multirow{2}{*}{$a_{13}$}
                            & $c_{13}$  \\
        \cline{3-3}\cline{5-5}\cline{7-7}
        & \mcc & \mcc & \mcc            \\
        \cline{2-7}

            & $c_{21}$
                & \multirow{2}{*}{$a_{22}$}

  • That worked. The problem was that my LaTeX system was too old. I updated my LaTeX installation from TeXLive 2016 to TeXLive 2019, and everything worked fine (including my previous code). But you are right that I could have made the code shorter (I was too involved in trying to get it working). Thanks!

Look, ma! No multirow! ;-)

\documentclass{article}
\usepackage{array,hhline}

\newcommand{\corner}[1]{%
  \begin{array}{@{}|c}
  #1\vphantom{\Big|}\\
  \hhline{|-}
  \multicolumn{1}{c}{\vphantom{\Big|}}\end{array}%
}
\newcommand{\entry}[1]{\quad#1\quad}

\begin{document}

$\begin{array}{@{}r@{\hspace{\arraycolsep}\vline}*{3}{c@{\vline}}}
 \multicolumn{1}{@{}c@{}}{}& \multicolumn{1}{c}{H1} & \multicolumn{1}{c}{H2} & \multicolumn{1}{c}{H3} \\
 \hhline{~|---}
 L1 & \entry{a_{11}}\corner{c_{11}}  & \entry{a_{12}}\corner{c_{12}} & \entry{a_{13}}\corner{c_{13}} \\
 \hhline{~|---}
 L2 & \entry{a_{21}}\corner{c_{21}}  & \entry{a_{22}}\corner{c_{22}} & \entry{a_{23}}\corner{c_{23}} \\
 \hhline{~|---}
 \end{array}$

A version of your tabular typeset using cals. This version two mimics the column width in the question (10mm/6mm+2tabcolsep+arrayrulewidth):

\newcommand{\corner}{\dimexpr(6mm+12.4pt)\relax}          % Same column width as in the question
