缺少页脚问题

Question

我正在尝试为第一页设置不同的页眉和页脚来格式化我的文档。我成功地为第一页设置了页眉和页脚，但第二页的页脚不可见。我认为第二页的页边距以某种方式发生了变化。你能帮我解决这个问题吗？以下是代码。

\documentclass[times,10pt,twocolumn]{cls/IEEEtran}

\usepackage{graphicx}
\usepackage{authblk}
%============== For header and footer
\usepackage{fancyhdr}
\pagestyle{fancy}
%  --------   Normal Headers
\lhead{\textbf{\thepage}}
\chead{Paper Title: Modeling Reliability of the Grid}
\rhead{}
\lfoot{Copyright \textcopyright 2014 MECS}
\cfoot{}
\rfoot{\emph{I.J. Computer Network and Information Security}, 2014, vol, issue, pages}
\renewcommand{\headrulewidth}{0pt} % to remove line on header
\renewcommand{\footrulewidth}{0pt} % to remove line on footer

% ----------------------------define new page style for first page
\fancypagestyle{first}{
\fancyhf{} % clear all header and footer fields

Answer 1

您的第一个页眉太高，这导致fancyhdr从第二页开始增加页眉高度。

您可以通过假装第一个标题没有高度来修复它：

\documentclass[10pt,twocolumn]{IEEEtran}

\usepackage{graphicx}
\usepackage{authblk}

%============== For header and footer
\usepackage{fancyhdr}
\pagestyle{fancy}
%  --------   Normal Headers
\fancyhf{} % clear all fields
\fancyhead[L]{\bfseries\thepage}
\fancyhead[C]{Paper Title: Modeling Reliability of the Grid}
\fancyfoot[L]{Copyright \textcopyright 2014 MECS}
\fancyfoot[R]{\emph{I.J. Computer Network and Information Security}, 2014, vol, issue, pages}
\renewcommand{\headrulewidth}{0pt} % to remove line on header
\renewcommand{\footrulewidth}{0pt} % to remove line on footer

% ----------------------------define new page style for first page
\fancypagestyle{first}{%
  \fancyhf{}% clear all header and footer fields
  \fancyhead[L]{\JournalDataAndLogo}%
  \fancyfoot[L]{Copyright \textcopyright 2014 MECS}%
  \fancyfoot[R]{\emph{I.J. Computer Network and Information Security}, 2014, vol, issue, page}%
  \renewcommand{\headrulewidth}{0pt}% to remove line on header
  \renewcommand{\footrulewidth}{0pt}% to remove line on footer
}

\newcommand{\JournalDataAndLogo}{%
  \leavevmode\smash{%
    \raisebox{-2ex}{% <----- adjust to suit
      \begin{tabular*}{\textwidth}{@{\extracolsep{\fill}}lr@{}}
        \begin{tabular}[b]{@{}l@{}}

        &
        \includegraphics[width=2.5cm,height=1.5cm]{example-image.pdf}
     \end{tabular*}%
    }% end of \raisebox
  }% end of \smash

由于我没有您的徽标，所以无法知道它的垂直尺寸；请2ex在标记的位置进行调整。
