[Tex/LaTex] Referencing a table in latex

captionscross-referencingtables

My latex document is given below.

\documentclass[12pt]{report}
\linespread{}
\usepackage{fancyhdr}
\usepackage{amsmath,amssymb}
\usepackage{caption}
\usepackage{relsize}
\usepackage[font={small,it}]{caption}

\usepackage{changepage}
\usepackage[textwidth=16cm,textheight=24cm,margin=2cm]{geometry}
\usepackage[colorlinks,citecolor=red]{hyper ref}
\hypersetup{colorlinks=true, linkcolor=blue}
\usepackage{titlesec}
\titleformat{\chapter}[display]{\Large\centering}{Chapter \thechapter:}{0pt}{}{}
\titleformat{\section}{\large\bfseries}{\thesection}{1em}{}
\titleformat{\subsection}{\large\bfseries}{\thesubsection}{1em}{}
\titleformat{\subsubsection}{\large\bfseries}{\thesubsubsection}{1em}{}
\pagestyle{fancy}
\fancyhead[RE,RO]{}
\fancyhead[LO,RE]{\itshape \nouppercase \leftmark}
\usepackage{float}
\restylefloat{table}
\usepackage[table]{xcolor} 
\setlength{\arrayrulewidth}{1mm}  
\renewcommand{\arraystretch}{1.2} 
\setlength{\tabcolsep}{0.5cm} 
\usepackage{booktabs}
\usepackage{tabularx}
\usepackage{array}
\usepackage{lmodern}
\usepackage{microtype} 
\usepackage{siunitx}
\begin{document}
\begin{table}[h]
\caption{Parameters}
\begin{tabular}{ p{6cm} p{4cm} p{4cm}  }    
\hline \\ 
\textsc{Demo 1} \\
Characteristics & \textsc{Water} & \textsc{Air}    \\ 
\hline 
Density & 1000 & 1.25 \\
State  &  liquid & Gas \\
\hline
\end{tabular}
\caption*{Table 1}
\label{table1}
\end{table}
\end{document}

In the above table I would like to make reference to the table using the "table1" label in the code. However, when I use \ref{table1}, it does not seem to refer me to the table. Also, The first caption on top (\caption{Parameters}) does not seem to appear in my table. I would really appreciate any help with these issues. I must be missing something quite obvious.

Thanks

\restylefloat causes the caption positioning problem and \label after \caption*{} is useless!

[Tex/LaTex] cross referencing papers in a table

I think egreg is correct that the back-referencing gets confused but it does not seem to be a result of back-referencing a citation in a float per se.

The problem occurs only if the relevant counter needed for the reference has not yet been incremented by the \caption... command. Placing this before the table resolves the referencing issue:

Note that the 'document' tag is the back-reference for the citation in the text; the '1' is the back-reference for the citation in the table, as can be seen if the citation in the text is removed:

I don't know much about back-referencing, but I assume the complete lack of document structure is part of the problem since adding a \section{section} command also makes it disappear:

\documentclass{article}
\usepackage[numbers, sort]{natbib}
\usepackage[font=footnotesize, labelfont=bf]{caption}
\usepackage[backref, pageanchor=true, plainpages=false, pdfpagelabels, bookmarks, bookmarksnumbered]{hyperref}
\begin{document}
%\section{Section}\label{sec:sec}% uncomment this to eliminate the back-reference tagged 'document'
\begin{table}[t]
\centering
\caption[short caption]{long caption}
\label{tab:label}
\begin{tabular}{ c | l }
  \citep{article-full} & cell\\
\end{tabular}
\end{table}
citation in text \citep{article-full}.% or comment this line instead
\bibliographystyle{plainnat}
\bibliography{xampl}
\end{document}

Note that I've moved the \label as well, but this isn't actually important: what matters is the move of the \caption command.

Heiko Oberdiek suggests that if your document doesn't have the structure of sectional divisions at all, then pagebackref may be a better option than backref:

\usepackage[pagebackref, pageanchor=true, plainpages=false, pdfpagelabels, bookmarks, bookmarksnumbered]{hyperref}

In that case, a document with the table on page 2 and a citation in the text on page 3 produces these back-references:

This is clearly preferable as far as in-text citations are concerned. However, in this case the reference to the citation in the table is linked to the relevant page rather than to the table specifically. Moreover, this option produces two back-references rather than just one, as would be the case with the same content within a sectional division. This might be an advantage or a disadvantage, of course, depending on your requirements.

You need \refstepcounter here. This not only steps the counter (similar to \stepcounter), but also updates the reference (stored in \@currentlabel):

\documentclass{article}

%\usepackage{hyperref}
\usepackage{amsmath}

\begin{document}

\begin{equation}
  f(x) = ax^2 + bx + c
\end{equation}

See Table~\ref{tab:test} and equation~\eqref{eq:tbl}.
\begin{table}
  \centering
  \caption{A table caption.}\label{tab:test}
  \begin{tabular}{llc}
    \hline
    \textbf{reference} & \textbf{correlation} \\
    \hline
    reference 1        & $a = b$  
                       & \refstepcounter{equation}(\theequation)\label{eq:tbl}
    \\
    \hline
  \end{tabular}
\end{table}

\end{document}

Note how the able example also highlights the problems you might be facing with manually setting an reference that is part of a float. The label may appear out-of-sequence with the rest of the text (where (2) appears before (1)).

The above example will also work with hyperref.
