我正在使用longtabu环境创建一个表格，总体外观几乎符合我的要求，但是我遇到了一些格式混乱的问题。以下是我想要做的：
如您所见，左侧和右侧的单元格multicolumn不再垂直居中，我不知道如何修复它。我以前makecell在表格中使用时遇到过类似的问题，我可以通过确保所有列都具有m正确对齐的属性来解决。但这似乎在这里不起作用。
此外，我希望能够动态计算四个组合列的宽度，而不必手动测量宽度，但我对 Latex 还不太熟悉，所以任何帮助都欢迎！以下是我到目前为止实现这一目标的方法，可能是我犯了一些不必要的错误，对 tex 还不太熟悉...
\begin{longtabu} to \textwidth
{@{}|X[-1,l,m]
|X[-1,l,m]
|X[l,m]
|X[-1,l,m]|
X[-1,l,m]|
X[-1,l,m]|
X[l,m]|>{\color{gray}}X[-1,c,m]| @{}}
\tabucline[1pt]-
\everyrow{\tabucline[0.5pt]-}
\rowcolor{light-gray} Name & Options & 3 & 4 & 5 & 6 & Attributes & Ref\\
\tabucline[1pt]-
\endhead
Name goes here & available options & Description & . & . & . & . & . \\
& Description of Option & \multicolumn{4}{l|}{\rlap{\parbox[t]{6.8cm}
{Here is supposed to be a very long text that is shown across
colums 3 to 6, combining 4 columns, however when combining columns
here the cells left and right of this text are no longer vertically
centered and I have to manually add the width of this box.}}}
& more attributes & ... \\
& Desc. 2 & & & & & \makecell{centered\\attributes\\seem to\\work here} &...\\
\end{longtabu}

这是使用包的表格，xltabular而不是longtabu已经推荐的Zarko 在评论中：
\documentclass{article}
\usepackage{geometry}
\usepackage[table]{xcolor}
\definecolor{light-gray}{RGB}{130,130,130}
\usepackage{xltabular}
\renewcommand\tabularxcolumn[1]{m{#1}}
\begin{document}
\begin{xltabular}{\textwidth}{|l|>{\raggedright\arraybackslash}X|l|l|l|l|>{\raggedright\arraybackslash}X|l|}
\hline
\rowcolor{light-gray} Name & Options & 3 & 4 & 5 & 6 & Attributes & \\ \hline
Name goes here & available options & Description & . & . & . & . & . \\
\hline
& Description of Option & \multicolumn{4}{m{5cm}|}{{Here is supposed to be a very long text that is shown across colums 3 to 6, combining 4 columns, however when combining columns here the cells left and right of this text are no longer vertically centered and I have to manually add the width of this box.}}
& more attributes & ... \\
\hline
& Desc. 2 & & & & & centered attributes seem to work here &...\\
\hline
\end{xltabular}
\end{document}
