[Tex/LaTex] Problem with Caption of a Table

captionstables

i am making a table in Latex. Everything is fine but the Caption section is not the way i want it to be.
I want the whole caption of the table in one single line, Not in two lines, the way it is right now as shown in the figure. I am doing it like this.

\begin{table}[h]
\caption {Parameters for Energy Model} 
\begin{center}
\footnotesize
\begin{tabular} {|r|c|}
\hline
\textbf{Parameter}      &   \textbf{Value}   \\
\hline
Power in recieving      &    5W     \\
\hline
Power in sleep mode     &   250mW (assumed 5\% of $P_{Rx}$) \\
\hline
RF efficiency           &   20\%    \\
\hline
Supply loss efficiency  &   10\%    \\
\hline
Cooling efficiency      &   50\%    \\
\hline
Max transmit power      &   5W      \\
\hline
Wakeup Energy           &   50J     \\
\hline
\end{tabular}
\end{center}
\end{table}

If you are not bound to the journal's policy on how to set such things, you might want to load the package caption which 'fixes' this for you. Note that the font-size of the caption is getting slightly bigger than before. Please read the manual of caption in order to see how to tweak such things. In order to change something just for the tables, it would look like \captionsetup[table]{...}. Edit: I inserted something which comes close to the default.

\documentclass{IEEEtran} 
\usepackage{caption}
\captionsetup[table]{font={small,sc},labelsep=colon}
\usepackage{siunitx}
\usepackage{booktabs}

\begin{document}
\begin{table}[h]
    \centering
    \caption {Parameters for Energy Model} 
        \footnotesize
        \begin{tabular}{ll}
            \toprule
            \textbf{Parameter} & \textbf{Value} \\
            \midrule
            Power in recieving & \SI{5}{\watt} \\
            Power in sleep mode & \SI{250}{\milli\watt} (assumed \SI{5}{\percent} of $P_{Rx}$) \\
            RF efficiency & \SI{20}{\percent} \\
            Supply loss efficiency & \SI{10}{\percent} \\
            Cooling efficiency & \SI{50}{\percent} \\
            Max transmit power & \SI{5}{\watt} \\
            Wakeup Energy & \SI{50}{\joule} \\
            \bottomrule
        \end{tabular}
\end{table}

[Tex/LaTex] Table and Figure Caption Citation Problem

After processing your document, you will receive the following warning:

LaTeX Warning: Citation `whatever' on page 1 undefined on input line 3.

which gives you a hint about the cause of the problem: you are using \cite and you should be using \ref instead (the output [?] also indicates that a citation was incorrectly expected). Simply replace:

Some text cites Table \cite{whatever}

with

Some text cites Table~\ref{whatever}

\cite is for bibliographical citations.

[Tex/LaTex] How to caption/subcaption a tabular? easily

Repeating the suggestions provided in the comments: Place the existing tabular environment inside a table environment. It is common -- though not mandatory -- to center the material inside a table environment. The command \centering achieves that objective. The table and figure environments are "floats", i.e., unless you explicitly instruct LaTeX not to do so, LaTeX will place them where it thinks it's best. For much more on floats and the LaTeX algorithm that determines float placement, see the posting How to influence the position of float environments like figure and table in LaTeX?

The table environment can be given a \caption and a \label. Assigning labels is useful if you want to cross-reference the table somewhere else in your document using the TeX/LaTeX command \ref.

If you do a lot of cross-referencing -- not only to tables, but to sections, figures, page numbers, etc -- you may want to get to know the cleveref package and its command \cref. For more on LaTeX's cross-referencing mechanisms and packages that provide enhanced cross-referencing macros see the posting Cross-reference packages: which to use, which conflict?

Here, finally, is your tabular environment encased in a table environment, with a couple of cross-referencing commands thrown in for good measure.

\documentclass[12pt,a4paper,x11names]{article}
\usepackage[vmargin=2.5cm, left=3.5cm, right=2.5cm] {geometry}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[spanish]{babel}
\usepackage[spanish]{cleveref} %% new

\begin{document}
Hello, \dots

\begin{table}[h]  %% new
\centering        %% new
\caption{A simple table} %% new
\label{tab:simple}       %% new
\begin{tabular}{|c|c|r|}
  \hline
  % after \\: \hline or \cline{col1-col2} \cline{col3-col4} ...
  a & e & 12 \\
  \hline
  f & g & 3 \\
  \hline
\end{tabular}
\end{table} %% new

Here's a cross-reference to table \ref{tab:simple}.  %% new

Here's a cross-reference to \cref{tab:simple}.  %% new
\end{document}
