在 \multirow 中对齐方程

Question

我想对齐此文本。对于计算表，我需要统一的输入以便重复使用。

这是我的代码：

% Document Class
% **************************************************
\documentclass[
    paper=A4,                   %
    11pt,                       % font size
]{scrreprt}                     %

\RequirePackage{tabularx}       % table features
\RequirePackage{textcomp}       % different symbols
\usepackage{tikz}               % check marks
\usepackage{amssymb}            % for calculations
\usepackage{datatool}           % tools to load and manipulate data
\usepackage{array,multirow}     % for calculations

\begin{document}

\newenvironment{conditions*}
    {\par\vspace{\abovedisplayskip}\noindent
    \tabularx{\columnwidth}{

    }}{\endtabularx\par\vspace{\belowdisplayskip}}
   
\def\s{454}
\def\k{0.00394}

        & & & t_{req}
        & 1.78876
        & \mathrm{mm} \\
\end{conditions*}

\end{document} ```

Answer 1

将可选的对齐添加[t]到所有命令的前面\multirow：

\multirow[t]{2}{*}{Required thickness} & 
\multirow[t]{2}{*}{$t_{req}$}
\multirow[t]{2}{*}{
    $\begin{aligned}[t]
    & = k \times  s \\
    & = \k \times  \s \\
    & = 1.78876
    \end{aligned}$}
