I'm writting this table:

\caption{$\sigma(gg\to H \to X X^*)\mbox{fb}$ in $SU(5)_{eff}$ model at $\sin \beta \sim \sin \alpha$, $m_S$= 500 GeV, $Y_4=0.66- 0.69$, $k_i=10$, and $\zeta=-10$.}
Channel   & $~ \sigma(gg\to H \to X X^*)~ \mbox{fb}~ $ & Exp. upper bound ~ fb  \\ [0.5ex]
$WW^*$ & 11 &  54   \\
ZZ & 5 & 12  \\
$t\bar{t}$ & 148    &  550   \\
hh & 4  & 35    \\
jj & 5  & 15    \\

The problem is that the Caption is corrupted by spaces like:

enter image description here

I don't know why this happens, the Captions in the other figures in the TeX file looks fine.


Here is my LaTeX file preamble:


%%%%%%%%%%%%%%%%%%%%% generic macros %%%%%%%%%%%%%%%%%%%%%%%
\topmargin      -1.cm  % distance to headers
\textwidth       170mm  % Horizontal alignment
\textheight      235mm  % height of text
\renewcommand{\baselinestretch}{1.12} \normalsize

\def\etal{{\it et al.}}
\def\eg{{\it e.g.}}
\def\ie{{\it i.e.}}
\newcommand{\x}[2]{#1 \times #2}
\newcommand{\mat}[1]{\begin{pmatrix} #1 \end{pmatrix}}

    Welcome, the reason most likely is hidden in your document preamble. Please provide a minimal working example.

  • In particular, please do tell us how wide the text block is.

  • When I try your preamble followed by your table and \end{document} I do not get the same caption as you have. Try to scale down your example and give a compilable code that reproduces the behavior.

  • Even with the preamble, the error will not reproduce for me. Just as an experiment, try removing the caption package. Commented Jun 26, 2016 at 13:33

One problem of your given code is that it is not minimal or compilable as presented in your question. So I stripped it down to have only the relevant parts inside the code.

The second problem is that you call package caption with "bad" result. If you have a look into the log file you will find something like that:

Package caption Warning: Unsupported document class (or package) detected,
(caption)                usage of the caption package is not recommended.
See the caption package documentation for explanation.
Package caption Info: Begin \AtBeginDocument code.
Package caption Info: Incompatible package detected (regarding \caption).
(caption)             \caption = macro:->\minipagefootnote@here \ifx \@captype \@undefined \@latex@error {\noexpand \cap
tion outside float}\@ehd \expandafter \@gobble \else \refstepcounter \@captype \expandafter \@firstofone \fi {\@dblarg {
\@caption \@captype }}.

Package caption Warning: \caption will not be redefined since it's already
(caption)                redefined by a document class or package which is
(caption)                unknown to the caption package.
See the caption package documentation for explanation.

Package caption Info: End \AtBeginDocument code.

To make it short: Do not load package caption with this class!

With the following shortened MWE

% twocolumn,

\topmargin      -1.cm  % distance to headers
\textwidth       170mm  % Horizontal alignment
\textheight      235mm  % height of text
\renewcommand{\baselinestretch}{1.12} \normalsize

\usepackage{caption} % <================================================



Test text.

  $\sin \beta \sim \sin \alpha$, $m_S$= 500 GeV, $Y_4=0.66- 0.69$, 
  $k_i=10$, and $\zeta=-10$.}

Test text2. See table~\ref{tab:tab1}.


I get the following resulting pdf (with the shown messages above):

You can see that the table caption shows not the spaces you have.

After commenting the call of package caption I get the following resulting pdf (without the warning for package caption):

You see the difference?

Please study my changed MWE, I changed a lot of things. At last you called several packages twice (Do not do this!) and left not used commands in the code I deleted too.

At last I added command \listfiles as first line to get an list of all used packages and version numbers for the compiling of the MWE. Please compare the following list with the result on your system. I guess your system is outdated causing the problem you have:
