Graphics, Figures & Tables ⇒ cross-reference to cell inside table

[fatra2]

Hi there,

I have a document with a very, very long table, over many pages. Therefore, making a reference to this table is quite ridiculous.

Is there a way to make a reference to a particular cell/row in LaTeX???

I tried making sections and subsections inside the table, but the compiler complains.

Thank you in advance. Cheers

The complaint is no surprise. But you need a command that generates an anchor for the reference. I'm not aware of a method to do that inside a table.

But I can offer a workaround. You could mark a single cell or a row with a certain color by using the colortbl package. A small colored box in the describing text could be done with pgf/tikZ as some kind of reference. Consider the following example.

Code: Select all

\documentclass[11pt,a4paper,english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage{babel}
\usepackage[font=small,labelfont=bf,tableposition=top]{caption}
\usepackage{array,multirow}
\usepackage[svgnames,table]{xcolor}
\usepackage{tikz}
\usepackage{blindtext}

\parindent0em

\begin{document}
  \blindtext

  \begin{table}[!ht]
    \caption{A table with a colored row for reference}\label{tab:colorrow}
    \centering
    \begin{tabular}{*{4}{c}} \hline
      Some Text & Some Text & Some Text & Some Text \\ \hline
      Some Values & Some Values & Some Values & Some Values \\
      Some Values & Some Values & Some Values & Some Values \\
      \rowcolor{gray!25}
      Some Values & Some Values & Some Values & Some Values \\
      Some Values & Some Values & Some Values & Some Values \\
      Some Values & Some Values & Some Values & Some Values \\
      Some Values & Some Values & Some Values & \cellcolor{gray!50} Some Values \\ \hline
    \end{tabular}
  \end{table}

  As seen in Table~\ref{tab:colorrow}, the values of a row could be referenced by color marks (\,\tikz\fill[gray!25] (0,0) rectangle (16pt,8pt);\,). Even single cells could be pointed out (\,\tikz\fill[gray!50] (0,0) rectangle (16pt,8pt);\,).

  \medskip
  \blindtext
\end{document}

The xcolor package has many more predefined colors. So you won't run out of stuff for your colored references.

Hi there,

Thank you for your proposition, but this is not precisely what I want. But through your comments, I search some more, and found a solution that suits me very well.

Everyone using LaTeX knows that you can label any part of text where LaTeX generates a number, like a table, equation, section... But my problem is that I want to make a reference to part of a table, which I cannot create a section from within.

My solution is to use the \phantomsection \label{mylabel} anywhere in my table. The \phantomsection is part of the hyperref package, and generates a phanton section (duh!!!) within my table.

It seems to work well. Cheers
