表格单元格中的 arraystretch 和数字的意外行为

Question

使用graphicx和includegraphics命令，我想在表格单元格中放置一个图形。此外，我使用 命令arraystretch增加单元格的填充。不幸的是，如果我使用 all in common，我会得到一个奇怪的对齐行为：

第二行的文本也应该与单元格顶部对齐。我几乎只使用了原生乳胶材料，所以我不认为这与包相关性有关。我做错了什么吗？谢谢！！

这是我的 MWE：

\documentclass[12pt,twoside,openright,a4paper,oldfontcommands]{memoir}

\usepackage{tabularx}
\usepackage[pdftex]{graphicx}
\usepackage[table]{xcolor}

\begin{document}

\newlength{\convetionsSymbolWidth}
\setlength{\convetionsSymbolWidth}{3.5cm}

\newlength{\convetionsDescriptionWidth}
\setlength{\convetionsDescriptionWidth}{\textwidth}
\addtolength{\convetionsDescriptionWidth}{-\convetionsSymbolWidth}
\addtolength{\convetionsDescriptionWidth}{4\tabcolsep}

\begingroup
    \renewcommand{\arraystretch}{1.9}
    \begin{table}[h!]
        \begin{tabular}{ >{\centering\arraybackslash}p{\convetionsSymbolWidth}
           p{\convetionsDescriptionWidth} }

Answer 1

使用

 \raisebox{\dimexpr-\height+2ex}{%
     \includegraphics[width=\marginparwidth]%
          {structureIconArtifactsProxyWorkload.pdf}}

Answer 2

另一种方法是使用包adjustbox并添加valign=t（垂直对齐顶部）到\includegraphic选项中。从包中删除 [demo]graphicx以获得真实图像

代码

\documentclass[12pt,twoside,openright,a4paper,oldfontcommands]{memoir}

\usepackage{tabularx}
\usepackage[pdftex,demo]{graphicx}           % remove demo for true image
\usepackage[table]{xcolor}
\usepackage[export]{adjustbox}               % <--- new 
\begin{document}

\newlength{\convetionsSymbolWidth}
\setlength{\convetionsSymbolWidth}{3.5cm}

\newlength{\convetionsDescriptionWidth}
\setlength{\convetionsDescriptionWidth}{\textwidth}
\addtolength{\convetionsDescriptionWidth}{-\convetionsSymbolWidth}
\addtolength{\convetionsDescriptionWidth}{4\tabcolsep}
