Graphics, Figures & Tables ⇒ Nice table without column

[cgnieder]

I have made the whole table to script size.

I'm quite sure there are better ways but until you give us a minimal working example (!) it's impossible to tell!

Would you please tell me how to increase the distance of two adjacent rows and two adjacent columns a little bit more?

There is more than one way: for example the space between columns can be adjusted using the @ specifier; and the space between rows can be changed in multiple ways, too. Which one is the best/right one in your case is hard if not impossible to say without the actual use case. So even if I begin sounding like a parrot: please provide a minimal working example.

I am writing the minimal code:

Code: Select all

\documentclass[11pt]{article}
\usepackage{caption}
\usepackage{booktabs,multirow,amsmath,amssymb,array}
\usepackage{siunitx}


\begin{document}
  \begin{table}[!ht]
    \caption{Markov channel parameter settings}
    \centering
    \label{tab:markovchapara}
		\scriptsize\addtolength{\tabcolsep}{-5pt}
    \begin{tabular}{
      c
      >{$}c<{$}
      @{~}
      >{$}c<{$}
			@{~}
      >{$}c<{$}
      @{~}
      >{$}c<{$}
    }\toprule
      \multirow{2}{*}[-0.5ex]{Channel $j$} & \multicolumn{2}{p{9em}}{A long, long, long line, that is broken}  & \multicolumn{2}{p{9em}}{A long, long, long line, that is broken 2} \\ \cmidrule(r){2-3}\cmidrule(l){4-5}
        & p_j                                     & q_j & \pi_{bj}                               & \pi_{ij} \\ \midrule
      1 & - \left( 2\,\alpha\,L-L+2\,\alpha-{\alpha}^{2} \right)     & {\lambda}^{2}+\Omega_{{1}}\lambda+\Omega_{{2}}     &\frac{\beta\,y^*\alpha}{\left( x^*+\alpha \right) ^{2}}   & -{\omega}^{2}+i\Omega_{{1}}\omega+\Omega_{{2}}  \\[2ex]
      2 & \left( L\,\beta\,\frac{\left( \beta-\gamma \right)}{\delta} +\,
\alpha\, \left(2\,L-\alpha-\alpha\,L \right)\right)     & -{\omega }^{2}+a_{{10}}b_{{01}}-\cos \left( \omega \,\tau  \right) a_{{01}}b_{{10}}     & \alpha\,L\, \frac{\left( \delta\,\alpha-\gamma\,\beta \right)}{\delta}    & -{ \omega} \left( a_{{10}}+b_{{01}} \right) +\sin \left( \omega \,\tau  \right) a_{{01}}b_{{10}}  \\
    \bottomrule
    \end{tabular}
  \end{table}
\end{document}

I want to get my code little bit compact and I need the distance of rows and columns (especially between 2rd & 3rd column) more.

Here is an idea using tabu. Maybe this get's you further.

Code: Select all

\documentclass[11pt]{article}
\usepackage{caption}
\usepackage{booktabs,multirow,amsmath,amssymb,array}
\usepackage{siunitx}
\usepackage{tabu}

\begin{document}

\begin{table}[!ht]
  \caption{Markov channel parameter settings}
  \label{tab:markovchapara}
  \small\tabulinesep=1mm
  \begin{tabu} to \linewidth {X[1.5c]X[$2C]X[$2C]X[$2C]X[$2C]}
   \toprule
    \multirow{2}{*}[0.5ex]{Channel $j$} &
    \multicolumn{2}{p{\dimexpr 7\linewidth/19\linewidth-5\tabcolsep}}{A long, long, long, long, long line, that is broken} &
    \multicolumn{2}{p{\dimexpr 7\linewidth/19\linewidth-5\tabcolsep}}{A long, long, long, long, long line, that is broken} \\
   \cmidrule(r){2-3}\cmidrule(r){4-5}
     & p_j & q_j & \pi_{bj}   & \pi_{ij} \\
   \midrule
    1 & - \Bigl( 2\,\alpha\,L - L + 2\,\alpha -\alpha^{2} \Bigr)
      & \lambda^{2}+\Omega_{1}\lambda + \Omega_{2}
      & \frac{\beta\,y^*\alpha}{( x^* + \alpha )^{2}}
      & -{\omega}^{2}+i\Omega_{{1}}\omega+\Omega_{{2}}  \\
    2 & \Bigl( L\,\beta\,\frac{\beta-\gamma}{\delta} + \alpha \bigl(2\,L-\alpha-\alpha\,L \bigr)\Bigr)
      & -\omega^{2} + a_{10}b_{01} - \cos(\omega\,\tau) a_{01}b_{10}
      & \alpha\,L\, \frac{\delta\,\alpha - \gamma\,\beta}{\delta}
      & -\omega ( a_{10} + b_{01} ) +\sin(\omega\,\tau) a_{01}b_{10}  \\
   \bottomrule
   \tabuphantomline
  \end{tabu}
\end{table}

\end{document}

Thanks for the code. I have installed the tabu, but I am getting 100 errors. I have attached here the log file.

[cgnieder]

Have you used the exact same code? If not please do so see if the code works for you.

If yes I am not sure what is going wrong. I can at least see that you have outdated versions of l3kernel, l3packages and siunitx. Try to leave the latter out of the example as it is not needed here anyway.

The important error is the first one:

! Package calc Error: `\linewidth ' invalid at this point.

See the calc package documentation for explanation.
Type H <return> for immediate help.
...

l.31 \end{tabu}

IIRC the older l3kernel used the calc so this might be the cause, but ...
