如何阻止 extrarowheight 影响第一行

Question

我曾经extrarowheight在只包含文本的表格中在行之间添加一些额外的空间。虽然这很有效，但也会影响第一行。有没有办法阻止这种情况，或者只删除第一行中的额外间距？我意识到我可以用不同的方式实现行之间的空间，但如果可能的话，我想避免这种情况。蓝色箭头表示我想要减少的空间。

这是屏幕截图和 MWE。

\documentclass[12pt, a4paper]{memoir}
\usepackage[utf8]{inputenc}

\settypeblocksize{237mm}{150mm}{*} % size of text block on page

\begin{document}

\begin{table}[!htb]
\caption{Severity of identified problems and proposed changes}
\label{some_changes}
\setlength{\extrarowheight}{5mm} %add row padding
\begin{tabular}{>{\raggedright}p{3.5cm} >{\raggedright}p{8.5cm} p{1.5cm}}
\toprule
Change & Justification & Severity\\
\midrule
1. \parbox[t]{3cm}{\raggedright A few meaningful definitions} &
Just some sample text that is longer than a couple of lines. This text has 
no meaning, it's just a sample text and does not do anything but fill some 
space here. & 
High\\
2. \parbox[t]{3cm}{\raggedright Some other thing that needs a change} &
Just some sample text that is longer than a couple of lines. This text has 
no meaning, it's just a sample text and does not do anything but fill some 
space here. & 
Medium\\
3. \parbox[t]{3cm}{\raggedright Some other thing that needs a change} &
Just some sample text that is longer than a couple of lines. This text has 
no meaning, it's just a sample text and does not do anything but fill some 
space here. &  
Low\\
\bottomrule
\end{tabular}
\end{table}

\end{document}

另一种解决方案：

\documentclass[12pt, a4paper]{memoir}
\usepackage[utf8]{inputenc}

\settypeblocksize{237mm}{150mm}{*} % size of text block on page

\begin{document}
\begin{table}[!htb]
\caption{Severity of identified problems and proposed changes}
\label{some_changes}
\setlength{\extrarowheight}{5mm} %add row padding
\begin{tabular}{>{\raggedright}p{3.5cm} >{\raggedright}p{8.5cm} p{1.5cm}}
\toprule
\\[-3\normalbaselineskip] % <------------- Add this
Change & Justification & Severity\\
\midrule
1. \parbox[t]{3cm}{\raggedright A few meaningful definitions} &
Just some sample text that is longer than a couple of lines. This text has 
no meaning, it's just a sample text and does not do anything but fill some 
space here. &

2. \parbox[t]{3cm}{\raggedright Some other thing that needs a change} &

\end{tabular}
\end{table}
\end{document}

主要思想是在 后添加一个负间距，\toprule以抵消 从 添加的填充\extrarowheight。添加

\\[-3\normalbaselineskip]

似乎将第一行恢复到其原始高度（无填充）。但当然，您随时可以将方括号中的值更改为您想要的任何值。

\addlinespace[5mm]从包裹中使用booktabs对您来说是一个可以接受的选项吗？

\documentclass[12pt, a4paper]{memoir}
\usepackage[utf8]{inputenc}

\settypeblocksize{237mm}{150mm}{*} % size of text block on page

\usepackage{lipsum}
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}

\begin{document}
    \begin{table}[htb]
\caption{Severity of identified problems and proposed changes}
\label{some_changes}
\begin{tabular}{>{\raggedright}p{0.6cm}@{\ }>{\raggedright}p{3cm} >{\raggedright}p{8.5cm} p{1.5cm}}
\toprule
\multicolumn{2}{l}{Change} & Justification & Severity\\

\end{tabular}
