I'm preparing a document using the book class. In the table of contents, the space between the subsection number and title is too wide. How to reduce it?

Without any packages:
In the standard documentclass without the influence of a package like titletoc you have to redefine the command \l@subsection. In the file book.cls you find the following settings:
\newcommand*\l@section{\@dottedtocline{1}{1.5em}{2.3em}} \newcommand*\l@subsection{\@dottedtocline{2}{3.8em}{3.2em}} \newcommand*\l@subsubsection{\@dottedtocline{3}{7.0em}{4.1em}} \newcommand*\l@paragraph{\@dottedtocline{4}{10em}{5em}} \newcommand*\l@subparagraph{\@dottedtocline{5}{12em}{6em}} The command \@dottedtocline expects the following parameters:
\renewcommand{\l@<typ>}{\@dottedtocline{<level>}% {<indentation>}% {<numwidth>}} To reduce the indentation of subsection you can do:
\makeatletter \renewcommand*\l@subsection{\@dottedtocline{2}{1.8em}{3.2em}} \makeatother Example:
\documentclass{book} \makeatletter \renewcommand*\l@subsection{\@dottedtocline{2}{1.8em}{3.2 em}} \makeatother \begin{document} \tableofcontents \chapter{foo} \section{bar} \subsection{foobar} \end{document} The method is equal for floating environments. The standard class book.cls provides \l@figure and and \l@table with the following settings:
\newcommand*\l@figure{\@dottedtocline{1}{1.5em}{2.3em}} \let\l@table\l@figure Package titletoc
By using the package titletoc you can set the indentation using \dottedcontents:
\dottedcontents{<section>}[<left>]{<above-code>} {<label width>}{<leader width>} Example
\documentclass{book} \usepackage{titletoc} \dottedcontents{subsection}[5.5em]{}{3.2em}{1pc} \begin{document} \tableofcontents \chapter{foo} \section{bar} \subsection{foobar} \end{document} The argument <section> can be somewhat irritating. The argument allows the name without a leading backslash so that figure and table are allowed, too.
Package tocloft
The package tocloft offers more than the following setting. The indentation is set by the length \cftXindent. The X stands for:
- part for
\parttitles - chap for
\chaptertitles - sec for
\sectiontitles - subsec for
\subsectiontitles - subsubsec for
\subsubsectiontitles - para for
\paragraphtitles - fig for
figure \captiontitle - tab for
table \captiontitles
Example:
\documentclass{book} \usepackage{tocloft} \setlength{\cftsubsecindent}{2em} \begin{document} \tableofcontents \chapter{foo} \section{bar} \subsection{foobar} \end{document} With a recent version of KOMA-Script one can use \RedeclareSectionCommand to change the entries in the table of contents as well. You can use that for all defined sectioning commands.
\documentclass{scrbook} \RedeclareSectionCommand[% tocindent=9em,tocnumwidth=7em,]{subsection} \begin{document} \tableofcontents \chapter{foo} \section{bar} \subsection{foobar} \end{document} The modification of figure and table is equal to the standard class and defined as follow:
\newcommand*\l@figure{\@dottedtocline{1}{1.5em}{2.3em}} \let\l@table\l@figure Package tocstyle (link in German)
With recent versions of KOMA-Scrpt, many parts of tocstyle are unneeded. It will be completely incorporated in KOMA-Script in the future.
To manipulate the toc (or other list of ...) in combination with a class of the KOMA bundle you should use the package tocstyle. The package is part of the KOMA bundle but with a separate documentation. The influence of the indentation is given indirectly by entryhook which can be set by \settocfeature
One of the benefits oftocstyle is the automatic calculation of the needed indentation.
Example:
\documentclass{scrbook} \usepackage{tocstyle} \usetocstyle{KOMAlike} \settocfeature[toc][2]{entryhook}{\protect\hspace*{-1.5em}\nobreakspace} \begin{document} \tableofcontents \chapter{foo} \section{bar} \subsection{foobar} \end{document} 
- 2tocstyle without option
tocindentmanualcalculates the needed indention itself, so to much indent shouldn't be. And the depth of subsection is AFAIK 2, so the second optional argument of\settocfeatureshould be 2 not 9. BTW: If the space after the number is to large you may change the featurespaceafternumber.Schweinebacke– Schweinebacke2011-11-06 15:48:01 +00:00Commented Nov 6, 2011 at 15:48 - @Schweinebacke: Welcome on stack exchange. I toke the wrong number ;-). Thanks. The
spaceafternumberinfluence the space between the number and the title. I want to reduce the intention in front of the section number.Marco Daniel– Marco Daniel2011-11-06 15:56:37 +00:00Commented Nov 6, 2011 at 15:56 - If added the information about
spaceafternumberonly, because I'm not sure if the OP wanted to change the indentation before the number or the indentation of the text, because there's a hanging indent after the number. It shouldn't be a critic to your excellent answer only an addendum.Schweinebacke– Schweinebacke2011-11-06 16:05:39 +00:00Commented Nov 6, 2011 at 16:05 - 3Since KOMA-Script version 3.16 you can use
\RedeclareSectionCommand[tocindent=1.8em,tocnumwidth=3.2em]{subsection}.esdd– esdd2016-03-18 23:43:18 +00:00Commented Mar 18, 2016 at 23:43 - 1
The macro in charge of setting the numbers and space between the titles is \numberline. It's defined in the LaTeX kernel as:
\def\numberline#1{\hb@xt@\@tempdima{#1\hfil}} \numberline{<stuff>} sets its argument <stuff> inside a box of width \@tempdima. The length \@tempdima is set by the macros \l@<type> that is responsible for setting any <type> within the ToC (like section, subsection, figure, etc.).
If you wish to have a natural separation between the numbers and titles within the ToC, you need to modify \numberline to not set its contents in a box, but rather just set the number followed by some space, as in:
\renewcommand{\numberline}[1]{#1~} The above redefinition will set the number followed by a ~ (tie). You can change this to suit your needs (\hspace{<len>}, :~, ...). Note that this will hold for for all elements that use it (including figures in the LoF and tables in the LoT).
\documentclass{article} \renewcommand{\numberline}[1]{#1~} \usepackage{lipsum}% Just for this example \AtBeginDocument{\sloppy}% Just for this example \begin{document} \tableofcontents \section{A section} \lipsum[1-50] \setcounter{section}{9} \section{Another section} \lipsum[1-50] \setcounter{section}{99} \section{Yet another section} \lipsum[1-50] \setcounter{section}{999} \section{Last section} \lipsum[1-50] \end{document} If you're using tocloft, a similar setup applies with some minor alterations, since tocloft allows for the insertion of content before and after the sectional unit numbering:
\usepackage{tocloft} \makeatletter \renewcommand{\numberline}[1]{{\@cftbsnum #1\@cftasnum~}\@cftasnumb} \makeatother 
You can use package tocbasic and reconfigure the ToC entries, to automatically detect the needed space for the numbers and the hierarchical indent:
\documentclass{article} \usepackage{tocbasic} \DeclareTOCStyleEntries[dynnumwidth,dynindent]{tocline}{section,subsection,subsubsection,paragraph,subparagraph}% Reconfigure ToC entries for section … subparagraph to use the needed number width and indent \usepackage{blindtext} \begin{document} \tableofcontents \blinddocument \setcounter{section}{9} \blinddocument \setcounter{section}{99} \blinddocument \setcounter{section}{999} \blinddocument \end{document} After two LaTeX runs the problem is still there:
But after at least three LaTeX runs you get:
If you work with a KOMA-Script class or a derived class instead of a standard class, you don't need to load tocbasic yourself, because the KOMA-Script classes already use this package. On the other hand, as you see in the example above, you don't need to use a KOMA-Script class to be able to use the features of tocbasic.
