我正在使用 Springer Nature 的乳胶模板，我的问题是当我使用双列选项（iicol）时，运行头的边距用完了，有人可以解决这个问题吗，请帮忙。

\section{Introduction}\label{sec1}
The Introduction section, of referenced text \cite{bib1} expands on the background of the work (some overlap with the Abstract is acceptable). The introduction should not include subheadings.
Springer Nature does not impose a strict layout as standard however authors are advised to check the individual requirements for the journal they are planning to submit to as there may be journal-level preferences. When preparing your text please also be aware that some stylistic choices are not supported in full text XML (publication version), including coloured font. These will not be replicated in the typeset article if it is accepted.

标头的编程sn-jnl.cls很马虎。替换该文件中的以下部分，它就可以正常工作。
\def\ps@headings{%
\def\@oddfoot{\hfill}%
\let\@evenfoot\@oddfoot%
%%\def\@evenhead{{\headerfont\thepage\qquad\rightmark\hfill\includegraphics{springer-nature-logo}}}%
%%\def\@oddhead{{\headerfont\includegraphics{springer-nature-logo}\hfill\leftmark\qquad\thepage}}%
\def\@evenhead{%
\vbox to 0pt{\vspace*{-39pt}%
\hbox to \hsize{\hfill Springer Nature 2021 \LaTeX\ template\hfill}}\par%%
\hspace*{-\textwidth}\hbox to \hsize{\headerfont\thepage\qquad\rightmark\hfill}}%
\def\@oddhead{%
\vbox to 0pt{\vspace*{-39pt}%
\hbox to \hsize{\hfill Springer Nature 2021 \LaTeX\ template\hfill}}\par%%
\hspace*{-\textwidth}\hbox to \hsize{\headerfont\hfill\leftmark\qquad\thepage}}%
\let\@mkboth\markboth%
}%
替换为
\def\ps@headings{%
\def\@oddfoot{\hfill}%
\let\@evenfoot\@oddfoot%
%%\def\@evenhead{{\headerfont\thepage\qquad\rightmark\hfill\includegraphics{springer-nature-logo}}}%
%%\def\@oddhead{{\headerfont\includegraphics{springer-nature-logo}\hfill\leftmark\qquad\thepage}}%
\def\@evenhead{%
\vbox to 0pt{\vspace*{-39pt}%
\hbox to \textwidth{\hfill Springer Nature 2021 \LaTeX\ template\hfill}}\par%%
\hspace*{-\textwidth}\hbox to \textwidth{\headerfont\thepage\qquad\rightmark\hfill}}%
\def\@oddhead{%
\vbox to 0pt{\vspace*{-39pt}%

\hspace*{-\textwidth}\hbox to \textwidth{\headerfont\hfill\leftmark\qquad\thepage}}%
\let\@mkboth\markboth%
}%
（所有出现的\hsize替换为\textwidth）
并替换
\def\ps@titlepage{%
%%\def\@oddhead{\vbox{\vskip-36pt\hbox to \textwidth{\hfill\includegraphics{springer-nature-logo}\hspace*{-1pt}}}}%
%%\let\@oddhead\@empty\let\@evenhead\@empty%
\def\@oddhead{%
\vbox to 0pt{\vspace*{-38pt}%
\hbox to \hsize{\hfill Springer Nature 2021 \LaTeX\ template\hfill}}}%%
\let\@evenhead\@oddhead%
\def\@oddfoot{\vbox to 18pt{\vfill\reset@font\rmfamily\hfil\thepage\hfil}}%%
\def\@evenfoot{}}%
\def\ps@plain{\let\@mkboth\@gobbletwo%
\let\@oddhead\@empty\let\@evenhead\@empty%
\def\@oddfoot{\vbox to 18pt{\vfill\reset@font\rmfamily\hfil\thepage\hfil}}%
\let\@evenfoot\@oddfoot}%
经过
\def\ps@titlepage{%
%%\def\@oddhead{\vbox{\vskip-36pt\hbox to \textwidth{\hfill\includegraphics{springer-nature-logo}\hspace*{-1pt}}}}%
%%\let\@oddhead\@empty\let\@evenhead\@empty%
\def\@oddhead{%
\vbox to 0pt{\vspace*{-38pt}%
\hbox to \textwidth{\hfill Springer Nature 2021 \LaTeX\ template\hfill}}}%%
\let\@evenhead\@oddhead%
\def\@oddfoot{\vbox to 18pt{\vfill\reset@font\rmfamily\hfil\thepage\hfil}}%%
\def\@evenfoot{}}%
\def\ps@plain{\let\@mkboth\@gobbletwo%
\let\@oddhead\@empty\let\@evenhead\@empty%
\def\@oddfoot{\vbox to 18pt{\vfill\reset@font\rmfamily\hfil\thepage\hfil}}%
\let\@evenfoot\@oddfoot}%
（也\hsize替换为\textwidth）
