使用 tabular 和 tabularx 以及 \hline 时放错了 \noalign

Question

我在 tabularx 末尾不断收到“Misplaced \noalign”错误。我已经在网上阅读了很多关于它的内容，例如你需要\\在 之前放置\hline。我这样做了，但仍然收到此错误。我希望有人能帮助我解决这个问题。

\begin{table}[!ht]
\newcolumntype{a}{>{\columncolor{LightGrey}}X}
\caption{caption}
\begin{tabularx}{\textwidth}{a|c|c|c|c|c|c|c|c|c|c|c|c|  }
    \rowcolor{White}
    & 
    \rowcolor{Blue}
    \textbf{\ref{F:1}} & \textbf{\ref{F:2}} & \textbf{\ref{F:3}} & \textbf{\ref{F:5}} & \textbf{\ref{F:6}} & \textbf{\ref{F:7}} & \textbf{\ref{F:8}} & \textbf{\ref{F:9}} & \textbf{\ref{F:10}} & \textbf{\ref{F:13}} \\ \hline
    \textbf{availablity} & \checkmark & o & x & x & x & x & x & x & x & x \\ \hline
\end{tabularx}
\begin{center}
\boldcheckmark = explicitly advertised, \checkmark = available, X = unavailable, O = non-identifiable
\end{center}
\end{table}

Answer 1

像这样？

• \columncolor用于对列进行着色
• \rowcolor只能位于行首，不能位于中间；
• \rowcolor超越columncolor
• \cellcolor用于为一个单元格着色，它会覆盖\rowcolor并column着色

\documentclass{article}

\usepackage[table, svgnames]{xcolor}
\usepackage{tabularx}
\usepackage{pifont}
\providecommand*{\checkmark}{\ding{51}}
\providecommand*{\boldcheckmark}{\textbf{\checkmark}}

\begin{document}
\begin{table}[!ht]
\setlength\extrarowheight{2pt}
\caption{caption}
\begin{tabularx}{\textwidth}{c | *{10}{>{\centering\arraybackslash}X|} }
\rowcolor{cyan!30}
\cellcolor{white}    
    & \textbf{\ref{F:1}} & \textbf{\ref{F:2}} & \textbf{\ref{F:3}} & \textbf{\ref{F:5}} 
    & \textbf{\ref{F:6}} & \textbf{\ref{F:7}} & \textbf{\ref{F:8}} & \textbf{\ref{F:9}} & \textbf{\ref{F:10}}& \textbf{\ref{F:13}} \\ \hline
\cellcolor{LightGrey}{availablity} & \checkmark & o & x & x & x & x & x & x & x & x \\ \hline
\end{tabularx}
\begin{center}
\boldcheckmark = explicitly advertised, \checkmark = available, x = unavailable, o = non-identifiable
\end{center}
\end{table}
\end{document}

Answer 2

或者像这样？此解决方案假定这两\rowcolor条指令都应该是真正的\cellcolor指令。

请注意，我故意省略了所有垂直和水平规则，因为它们除了造成视觉混乱之外什么也没有提供。

\documentclass{article}
\usepackage[table,svgnames]{xcolor}
\usepackage{tabularx,amssymb,bm}
\newcolumntype{a}{>{\columncolor{LightGrey}}X}
\providecommand\boldcheckmark{\bm{\checkmark}} 
\usepackage[skip=0.333\baselineskip]{caption} % optional

\begin{document}
\begin{table}[!ht]
\setlength\tabcolsep{5pt} % default: 6pt
\setlength\extrarowheight{2pt} % for a less-cramped "look"

\caption{caption}
\begin{tabularx}{\textwidth}{ a *{10}{c} @{}}
\cellcolor{White} &   % <-- was "\rowcolor{White}
\cellcolor{LightBlue} % <-- was "\rowcolor{Blue}"
\ref{F:1} & \ref{F:2} & \ref{F:3} & \ref{F:5}  & \ref{F:6} & 
\ref{F:7} & \ref{F:8} & \ref{F:9} & \ref{F:10} & \ref{F:13} \\ 
Availablity & \checkmark & o & x & x & x & x & x & x & x & x \\ 
\end{tabularx}

\medskip
\boldcheckmark = explicitly advertised, \checkmark = available, 
    x = unavailable, o = non-identifiable.
\end{table}
\end{document}
