\section 之后的 Marginnote：如何防止分页？

另一个更新：将 John Kormylo 的回答应用于 karlkoeller 的回答时使边注出现在两栏、双面文档的两侧，确保 后面\marginnote跟着%，并且\strut插入在 之前\begingroup（而不是直接在 之前\oldmarginnote）。否则，您将得到以下结果：

\documentclass[twocolumn,twoside]{article}
\usepackage{lipsum}
\usepackage{marginnote}
\makeatletter
\let\oldmarginnote\marginnote
\renewcommand*{\marginnote}[1]{%
    \begingroup%
        \ifodd\value{page}%
            \if@firstcolumn\reversemarginpar\fi%
        \else%
            \if@firstcolumn\else\reversemarginpar\fi%
        \fi%
        \strut%
        \oldmarginnote{#1}%
    \endgroup%
}
\makeatother
\begin{document}
    \lipsum[1-10]
    \section{Section}
    \marginnote{Note}%
    This text usually stays together, but is split across two columns with \verb|\marginnote|.
\end{document}

而不是这样：

\documentclass[twocolumn,twoside]{article}
\usepackage{lipsum}
\usepackage{marginnote}
\makeatletter
\let\oldmarginnote\marginnote
\renewcommand*{\marginnote}[1]{%
    \strut%
    \begingroup%
        \ifodd\value{page}%
            \if@firstcolumn\reversemarginpar\fi%
        \else%
            \if@firstcolumn\else\reversemarginpar\fi%
        \fi%
        \oldmarginnote{#1}%
    \endgroup%
}
\makeatother
\begin{document}
    \lipsum[1-10]
    \section{Section}
    \marginnote{Note}%
    This text stays together regardless of \verb|\marginnote|.
\end{document}

更新：这是一个更加简洁的 MWE：

\documentclass{article}
\usepackage{lipsum}
\usepackage{marginnote}
\begin{document}
    \lipsum[2-6]
    \section{Section}
    \marginnote{Note}
    This text should follow the section heading without a page break in between! Uncommenting \verb|\marginnote{Note}| fixes things.
\end{document}

所以我面临的问题与双栏文章无关needspace。但问题仍然相同：“如何防止章节标题和以下文本之间出现分页符？”

根据@karlkoeller 接受的答案使边注出现在两栏、双面文档的两侧，我想出了这个 MWE：

\documentclass[twoside]{article}

\usepackage{lipsum}
\usepackage[margin=2cm]{geometry}
\usepackage{marginnote}
\usepackage{needspace}

\makeatletter
\let\oldmarginnote\marginnote
\renewcommand*{\marginnote}[1]{%
   \begingroup%
   \ifodd\value{page}
     \if@firstcolumn\reversemarginpar\fi
   \else
     \if@firstcolumn\else\reversemarginpar\fi
   \fi
   \needspace{\baselineskip}\oldmarginnote{#1}%
   \endgroup%
}
\makeatother

\begin{document}
    \twocolumn
    \lipsum[2-10]
    \section{Section}
    \marginnote{Note}
    I am OK with the placement of the note, but I would like this text to follow the section heading without a page break in between! Note that uncommenting the \verb|\marginnote{Note}| fixes things.
\end{document}

如何防止章节标题和后续文本之间出现分页符？

答案1

这会将整个部分移至第 2 页。

\documentclass{article}
\usepackage{lipsum}
\usepackage{marginnote}
\begin{document}
    \lipsum[2-6]
    \section{Section}
    \strut\marginnote{Note}%
    This text should follow the section heading without a page break in between! Uncommenting \verb|\marginnote{Note}| fixes things.
    \end{document}

这会将注释和文本移至第 2 页，并将章节标题保留在第 1 页。

\documentclass{article}
\usepackage{lipsum}
\usepackage{marginnote}
\begin{document}
    \lipsum[2-6]
    \section{Section}
    \null\marginnote{Note}%
    This text should follow the section heading without a page break in between! Uncommenting \verb|\marginnote{Note}| fixes things.
    \end{document}
