Graphics, Figures & Tables ⇒ Table Lines and Caption Position

[moh-thabit]

Before I put my question, I searched in forum to find solution, I didn't get the answer. I am using a conference, IEEEtran document class as in this code.

Code: Select all

\documentclass[conference]{IEEEtran}
\usepackage{graphicx}
\usepackage{tabularx}
\usepackage{setspace}
\usepackage{hyperref}
\usepackage{float}
\usepackage{multirow}
\usepackage{booktabs}
\usepackage[switch, modulo]{lineno} % line numbering
\usepackage{epstopdf} % figures eps 
\usepackage{amsmath}

\begin{document}
  \begin{table}
    \scriptsize
    \begin{tabular}{llllllll}\toprule 
      Bus & Voltage & Angle & \multicolumn{2}{c}{Load} & \multicolumn{2}{c}{Generation} & Injected \\ \cline{4-5} \cline{6-7}
      No. & (p.u)   & (deg)   & MW &    MVar   &   MW   & MVar     & MVar  \\ \midrule

      5   &  0.996  & -3.989  &   125   &   50   &     0     &    0     &    0   \\
      6   &  1.013  & -3.688  &    90   &   30   &     0     &    0     &    0   \\
      7   &  1.026  &  3.719  &    0    &    0   &     0     &    0     &    0   \\
      8   &  1.016  &  0.727  &   100   &   35   &     0     &    0     &    0   \\
      9   &  1.032  &  1.966  &    0    &    0   &     0     &    0     &    0   \\
      Total &         &         &  315.0  &  115.0 &  319.954  &  22.833  &        \\ \bottomrule
    \end{tabular}
    \caption {Load flow results}
    \label{Load flow}
  \end{table}
\end{document}

My output table is shown:

table-output.png (29.74 KiB) Viewed 23177 times

I want to have a copy like in figure below, I did the same except the lines not separated between "Load" and "Generation" in \toprule, how I can make the line separated?

table-wanted.png (29.27 KiB) Viewed 23177 times

Other problem is the caption is more close to table, how I can make it little more down?

Hi there,

have a look at the example I adapted from your code.

Code: Select all

\documentclass[conference]{IEEEtran}
\usepackage{booktabs}
\usepackage{siunitx}

\begin{document}
  \begin{table}
%   \scriptsize
    \caption {Load flow results}
    \label{Load flow}
    \begin{tabular}{lSSSSSSl}\toprule
      {Bus} & {Voltage} & {Angle} & \multicolumn{2}{c}{Load} & \multicolumn{2}{c}{Generation} & {Injected} \\ \cmidrule(lr){4-5} \cmidrule(lr){6-7}
      No. & {(p.u)} & {(deg)} & {MW} & {MVar} & {MW} & {MVar} & {MVar} \\ \midrule
      1 & 1.040 & 0.0 & 0 & 0 & 71.594 & 27.032 & 0 \\
      2 & 1.025 & 9.279 & 0 & 0 & 163.0 & 6.657 & 0 \\
      3 & 1.025 & 4.664 & 0 & 0 & 85.0 & -10.856 & 0 \\
      4 & 1.026 & -2.217 & 0 & 0 & 0 & 0 & 0 \\
      5 & 0.996 & -3.989 & 125 & 50 & 0 & 0 & 0 \\
      6 & 1.013 & -3.688 & 90 & 30 & 0 & 0 & 0 \\
      7 & 1.026 & 3.719 & 0 & 0 & 0 & 0 & 0 \\
      8 & 1.016 & 0.727 & 100 & 35 & 0 & 0 & 0 \\
      9 & 1.032 & 1.966 & 0 & 0 & 0 & 0 & 0 \\[5pt]
      Total & & & 315.0 & 115.0 & 319.954 & 22.833 & \\ \bottomrule
    \end{tabular}
  \end{table}
\end{document}

The code button is extremely useful, it gives code markup and the ability to click on "Open with writeLaTeX". This ensures all of us seeing the same output.

Note the use of the siunitx package to align the numbers.

Tables have their captions above. And the class formats them correspondingly. So just put them there. Take a look at the IEEEtran manual to see how captions are placed for tables.

Sorry, I completely missed the caption part. Thorsten is right, a table caption goes on top.
I corrected my former post.

[moh-thabit]

Thank very much for both of you Johannes_B and localghost.

It works now but the table is span to the other column, how I control the size of table?

[Johannes_B]

Well, you could span it over both columns in the first place and center it.

Code: Select all

\documentclass[conference]{IEEEtran}
\usepackage{booktabs}
\usepackage{siunitx}
\usepackage{blindtext}
\begin{document}
\blindtext[12]

  % \scriptsize
    \caption {Load flow results}
    \label{Load flow}
    \begin{tabular}{lSSSSSSl}\toprule
      {Bus} & {Voltage} & {Angle} & \multicolumn{2}{c}{Load} & \multicolumn{2}{c}{Generation} & {Injected} \\ \cmidrule(lr){4-5} \cmidrule(lr){6-7}
      No. & {(p.u)} & {(deg)} & {MW} & {MVar} & {MW} & {MVar} & {MVar} \\ \midrule
      1 & 1.040 & 0.0 & 0 & 0 & 71.594 & 27.032 & 0 \\
      2 & 1.025 & 9.279 & 0 & 0 & 163.0 & 6.657 & 0 \\
      3 & 1.025 & 4.664 & 0 & 0 & 85.0 & -10.856 & 0 \\
      4 & 1.026 & -2.217 & 0 & 0 & 0 & 0 & 0 \\
      5 & 0.996 & -3.989 & 125 & 50 & 0 & 0 & 0 \\
      6 & 1.013 & -3.688 & 90 & 30 & 0 & 0 & 0 \\
      7 & 1.026 & 3.719 & 0 & 0 & 0 & 0 & 0 \\
      8 & 1.016 & 0.727 & 100 & 35 & 0 & 0 & 0 \\
      9 & 1.032 & 1.966 & 0 & 0 & 0 & 0 & 0 \\[5pt]
      Total & & & 315.0 & 115.0 & 319.954 & 22.833 & \\ \bottomrule
    \end{tabular}
  \end{table*}

You could change the size, but I wouldn't recommend it in you case.

[localghost]

[…] It works now but the table is span to the other column, how I control the size of table?

There are some measures you can take to evade this.

• In your example you have already decreased the font size by \scriptsize. Johannes seemingly commented this in his example.
• Johannes already introduced the S columns by siunitx. If you explicitly set the digit format for each column, only the necessary horizontal space is reserved.
• Modify the length \tabcolsep (default value 6pt) which determines the horizontal gap between the table columns.

All these points are incorporated in the below example.
