KOMA script - widening text width

I have a longtable that is about 14cm wide and the text width of 12 cm. Therefore I would like to widen the text width on two pages for 2 cm, toward the outer edge of the page. I have "discovered" that there are addmargin and addmargin* environments, but I just don't have a clue how to use them. I tried various combinations of parameters with no success. Any idea how to do that?

Thanks

I've got another solution, see below. I decided not to delete my answer dated October 19, 2013, because we found out that addmargin* won't work properly with longtable and \LTleft from the longtable package doesn't help much, either.

Maybe we can solve the issue the other way round: If you can put your longtable below a heading, then you could use \newgeometry starting from this heading with 20 mm less outer margin. To hide that, put your text inside an addmargin* environment, but not the table. Then restore the former geometry.

Looks like this:

\documentclass[11pt]{scrbook}
\usepackage{longtable, blindtext}

\begin{document}

\blinddocument

\newgeometry{paperwidth=210mm,paperheight=255mm,top=20mm,bottom=25mm,inner=25mm,outer=45mm,

\section{Tabulars}

This is not a perfect solution because of the pagebreak comming with \newgeometry and \restoregeometry, but maybe you can deal with it when you make the final layout.

• Thanks! I'll have a look at this solution. Fortunatelly, in my case longtable is actually part of a special subsection, which consists of the longtable and two lines of text. I'll still keep the question open in case someone comes with more general solution. – Pygmalion Oct 20 '13 at 10:40
• The problem with this solution is that it influences headers and footers. The longtable is safely within page, but header is now out of the page... :-( Also \restoregeometry is just in front of \tableofcontents, which creates one redundant empty page between. – Pygmalion Oct 20 '13 at 10:47
• @Pygmalion KOMA-script allows manipulation of the width of the header using \KOMAoptions for the affected pages, maybe it's a bit tricky. And if the longtable is the last part of your text just before the toc, maybe you won't need \restoregeomentry here or at all. – Keks Dose Oct 20 '13 at 10:57
• Correction: I solved the header problem simply by repeating the command \setheadwidth[0pt]{textwithmarginpar} just after \newgeometry. The problem of empty page between \restoregeometry and \tableofcontents remains! – Pygmalion Oct 20 '13 at 12:33
• Would you update your MWE? Because if I simply trade the last \blinddocument for a \tableofcontents, there is no empty page. – Keks Dose Oct 20 '13 at 12:48

[[ If nothing else helps one might consider to consult the manual (you get it with »texdoc komascript« on the command line, then search for »addmargin«). However:

\begin{addmargin*}[0cm]{-2cm}
\begin{longtable}...
...
\end{longtable}


If it does not work, please provide a MWE. ]]

I was wrong:

Edit

My apologies. You wrote, you had no clue and I misunderstood that.

Besides that, it's not sure that addmargin and longtable, see here, maybe you understand German. Markus Kohm provided an example for a solution without addmargin, but I did not check it:

\setlength{\LTleft}{-1cm}
\begin{longtable}{|c|c|c|}
\captionabove{Beschriftung der Tabelle}\\
Dies ist der Test & Dies ist der Test & Dies ist der Test \\
Dies ist der Test & Dies ist der Test & Dies ist der Test \\
Dies ist der Test & Dies ist der Test & Dies ist der Test \\
Dies ist der Test & Dies ist der Test & Dies ist der Test \\
Dies ist der Test & Dies ist der Test & Dies ist der Test \\
Dies ist der Test & Dies ist der Test & Dies ist der Test \\
Dies ist der Test & Dies ist der Test & Dies ist der Test \\
Dies ist der Test & Dies ist der Test & Dies ist der Test \\
Dies ist der Test & Dies ist der Test & Dies ist der Test \\
\end{longtable}


I found a post (http://www.komascript.de/node/1629) where Markus more or less says that a longtable inside an addmargin environment won't work.

• Of course I consulted the manual and first tried what you proposed above, and failed... I'll try to make a MWE then. – Pygmalion Oct 19 '13 at 19:57
• @Pygmalion See my edits: you were right and I was wrong. – Keks Dose Oct 19 '13 at 20:10
• The poblem with LTleft is that it translates to left on even and odd pages. It should translate to left on even pages and to right on odd pages. I speak too little German to understand this highly technical discussion. I don't see any documentation on LTleft. – Pygmalion Oct 19 '13 at 20:19
• LTleft is part of longtable and documented in the package documentation (but it works as you say, which isn't quite what you want) – David Carlisle Oct 19 '13 at 20:23
• @DavidCarlisle Thanks, I was searching KOMA manual :o/ – Pygmalion Oct 19 '13 at 20:24
