Graphics, Figures & Tables ⇒ ltablex | Caption of a multi-page Table

[maths-user]

I have got a problem with caption in combination with tabularx.
I try to create a multipage table that’s why I use the ltablex package and the tabularx environment. My example below is a shortened one-page table.
The table is to look like the first table below. It’s pretty fine that way. (By the way, I embedded the tabularx environment in a center environment to align the table with the regular text and the pageheadings. Is this the most elegant or best way to do it? And why is a table that is defined with the same width as the regular text not automatically aligned with the pageheadings and the regular text?)

The problem occurs when I try to add a table caption: in the second table with a caption not broad enough itself and in the third table a caption with defined width as a textline (that’s what I prefer). However, both examples are narrowing the table itself so that it is spread over many pages.

What’s the way to fix it?

(One further little question that came up when I created this example: the first table seems to have the internal counter 1 even without caption. What’s the way to avoid this?).

Thank you very much for your support!

Is there anybody who has got a solution for this problem?

I can't tell you what is going wrong. Perhaps a bug in the ltablex package. But I can offer a solution that uses the combination of the packages longtable and tabu.

Code: Select all

\documentclass[12pt,a4paper]{report}
\usepackage[T1]{fontenc}
\usepackage{booktabs,longtable,tabu}

\begin{document}
  This is a text at the beginning of the document which shows the width of a line.

  \begin{longtabu} to \linewidth {@{}rX@{}}\toprule
    & This is a long line containing a line break for demonstration of a table that has same width as regular text lines. \\
    $+$ & This is a second line. \\ \midrule
    $=$ & This is a preliminary sum. \\ \midrule
    $=$ & This is a third line to add. \\ \midrule
    $=$ & Result \\ \bottomrule
  \end{longtabu}

  \begin{longtabu} to \linewidth {@{}rX@{}}
    \caption{Table just for demonstration purposes with a very very long headline} \\ \toprule
    & This is a long line containing a line break for demonstration of a table that has same width as regular text lines. \\
    $+$ & This is a second line. \\ \midrule
    $=$ & This is a preliminary sum. \\ \midrule
    $=$ & This is a third line to add. \\ \midrule
    $=$ & Result \\ \bottomrule
  \end{longtabu}

  \setlength{\LTcapwidth}{\linewidth}
  \begin{longtabu} to \linewidth {@{}rX@{}}
    \caption{Table just for demonstration purposes with a very very long headline} \\ \toprule
    & This is a long line containing a line break for demonstration of a table that has same width as regular text lines. \\
    $+$ & This is a second line. \\ \midrule
    $=$ & This is a preliminary sum. \\ \midrule
    $=$ & This is a third line to add. \\ \midrule
    $=$ & Result \\ \bottomrule
  \end{longtabu}
\end{document}

For further details please refer to the manuals of the involved packages.

(One further little question that came up when I created this example: the first table seems to have the internal counter 1 even without caption. What’s the way to avoid this?).

As far as I know the »longtable« environment increments the table counter even without a caption, and so does the »tabularx« environment from ltablex. And the »longtabu« environment will do so, too. The longtable manual should tell you the details.
