fancyhead 左和右 [L] [R]，与 tabula 垂直不对齐

Question

我的头部左侧标题为“\leftmark \ \rightmark”，右侧标题为两行表格。但是，它们在垂直方向上并不对齐。如果我删除表格，只将右侧标题放在两条单独的行上，那么垂直对齐是正确的，但是我无法对齐学生姓名和学生编号。

作为表格，破坏了垂直对齐但具有良好的水平对齐：

\newcommand{\writer}{
    \begin{tabular}{l l}
        Student Name:& John Smith\\
        Student Number:& 42069420
    \end{tabular}
    }

使用换行符，没有表格，垂直对齐良好，但水平对齐不佳：

\newcommand{\writer}{
        Student Name: John Smith\\
        Student Number: 42069420
    }

下面包含一个最小工作示例，所有奇怪的额外代码都允许 \section{} 在章节页面上正确标记：

\documentclass{report}
\usepackage[utf8]{inputenc}
\usepackage{fancyhdr}
\usepackage{chngcntr}                           %defines \counterwithout    %does the sectionmark correctly
\usepackage{xpatch}                             %no idea??                  %does the sectionmark correctly
\usepackage{scrextend}                          %defines \Ifstr             %does the sectionmark correctly

%%%%%%%%%%Author deets (used in header)

    \begin{tabular}{l l}
        Student Name: John Smith\\
        Student Number: 42069420

欢迎来到 TeX、SE！

按照您对表中添加基线规范的定义：

\newcommand{\writer}{
    \begin{tabular}[b]{l l} % <--- table baseline is now at bottom line in the table
        Student Name:   &   John Smith\\
        Student Number: &   42069420
    \end{tabular}
    }

你将获得：
