在撰写论文时，我有一些章节的名称很长。使用 fancyhdr 指定页眉时，我将左侧（偶数）页设置为包含章节名称，将右侧（奇数）页设置为包含节名称。问题是，有时我的标题很长，页眉会分成两行。结果，第二行与页面左侧的页码对齐，而不是与文本对齐。像这样：
这是奇数页
因此，我想根据页眉上的红色垂直线对齐文本，然后将页码保留在最左侧（偶数页）或最右侧（奇数页）。偶数页的问题更为突出，但我也想解决奇数页的问题。

你可以重新定义花式头部：
\fancyhead[LE,RO]{\fontfamily{phv} \footnotesize \textsc \thepage }%
\fancyhead[RE]{\parbox[t]{0.95\textwidth}{\fontfamily{phv} \footnotesize \textsc \leftmark}}%
\fancyhead[LO]{\parbox[b]{0.95\textwidth}{\fontfamily{phv} \footnotesize \textsc \rightmark}}%
这会将页码放在页面的左侧（偶数）或右侧（奇数），并将标记括在 中parbox以限制其宽度。 的内容parbox可以是顶部对齐[t]或底部对齐[b]。
