Graphics, Figures & Tables ⇒ Table Column Width Adjustment

[erictamlam]

Dear all,

I have a serious problem adjusting the column widths of a table i created. What i tried to achieve is to split the last two combined columns ('transiton probabilites' and 'equilibrium distribution') equally between their subcolumns, i.e., 'p_j' and 'q_j' split the combined column 'transiton probabilites' equally, and so does '\pi_{bj}' and '\pi_{ij}'.
Any help would be deeply appreciated! Thanks in advance

    \caption{Markov channel parameter settings}
            \begin{tabular}{

                 S[tabnumalign=centre,tabformat=+1.2]|
                 S[tabnumalign=centre,tabformat=+1.2]|
                 S[tabnumalign=centre,tabformat=2]|
                 S[tabnumalign=centre,tabformat=2]

A belated answer, but perhaps still useful.

The trick is to drop the \multicolumn commands and slightly modify the table head instead. Furthermore it needs the correct specification for the number format in the S type columns. The below solution needs siunitx version 2.x (or higher).

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{caption}
\usepackage{booktabs,multirow}
\usepackage{siunitx}

\captionsetup{
  font=small,
  labelfont=bf,
  tableposition=top
}


\begin{document}
  \begin{table}[!ht]
    \caption{Markov channel parameter settings}
    \centering
    \label{tab:markovchapara}
    \begin{tabular}{    
      c
      S[table-format=1.2]
      @{~}
      S[table-format=1.2]
      S[table-format=1.3]
      @{~}
      S[table-format=1.3]
    }\toprule
      \multirow{2}{*}[-0.5ex]{Channel $j$} & {Transition} & {Probability} & {Equilibrium} & {distribution} \\ \cmidrule(r){2-3}\cmidrule(l){4-5}
        & {$p_j$} & {$q_j$} & {$\pi_{bj}$} & {$\pi_{ij}$} \\ \midrule
      1 & 0.1     & 0.4     & 0.2      & 0.8     \\
      2 & 0.2     & 0.6     & 0.25     & 0.75    \\
      3 & 0.3     & 0.7     & 0.3      & 0.7     \\
      4 & 0.3     & 0.5     & 0.375    & 0.625   \\
      5 & 0.35    & 0.65    & 0.35     & 0.65    \\
      6 & 0.4     & 0.6     & 0.4      & 0.6     \\
      7 & 0.6     & 0.6     & 0.5      & 0.5     \\
      8 & 0.6     & 0.4     & 0.6      & 0.4     \\ \bottomrule
    \end{tabular}
  \end{table}
\end{document}

It is suggestive to drop vertical lines in tables completely in order to improve their readability.
