我想要对下面的代码给出的表进行三处编辑。
首先，我希望列标题左对齐，并且列中的其余条目居中。
其次，我想将{\centering\arraybackslash}其放在最后一列标题中。（我没有在这段代码中添加它，因为有了它，代码就不会被编译。我从其他代码中看到我需要它，newline或者tabularnewline在某个地方需要它。显然，我不知道语法。）
第三，我没有看到表格右边缘的双竖线。
\documentclass{amsart}
\usepackage{adjustbox}
\usepackage{mathtools}
\usepackage{makecell}
\usepackage{array}
\begin{document}
\noindent \hspace*{\fill}
\setlength\extrarowheight{2pt}
\begin{tabular}{|| >{\centering\arraybackslash}l | >{\centering\arraybackslash}p{1.5cm} | >{\centering\arraybackslash}p{2.5cm} | >{\centering\arraybackslash}p{2cm} | >{\centering\arraybackslash}p{2cm} | p{3.5cm} ||} \hline
\multicolumn{5}{|| c ||}{\textbf{Inventory of Clocks and Frequency of Chimes}} \\ \Xhline{0.8pt}
& Number of clocks& Chimes $n$ times on the $n^{\mathrm{th}}$ hour & Chimes once on the hour & Chimes once on the half-hour \\ \hline
Type A & 10 & \checkmark & & \checkmark \\ \hline
Type B & 5 & \checkmark & & \\ \hline

\end{document}
答案1
\documentclass{amsart}
\usepackage{adjustbox}
\usepackage{mathtools}
\usepackage{makecell}
\usepackage{array}
\begin{document}
\centering
% no, use \centering \noindent \hspace*{\fill}
\setlength\extrarowheight{2pt}
% >{\centering\arraybackslash}l you can't apply paragraph settings to a `l`
% entry which is one-line.
% you only have 5 columns not 6, so I deleted the last p{}
\begin{tabular}{||l | >{\centering\arraybackslash}p{1.5cm} | >{\centering\arraybackslash}p{2.5cm} | >{\centering\arraybackslash}p{2cm} | >{\centering\arraybackslash}p{2cm} ||} \hline
\multicolumn{5}{|| c ||}{\textbf{Inventory of Clocks and Frequency of Chimes}} \\ \Xhline{0.8pt}
&
\raggedright Number of clocks&
\raggedright Chimes $n$ times on the $n^{\mathrm{th}}$ hour &
\raggedright Chimes once on the hour &
\raggedright\arraybackslash Chimes once on the half-hour \\ \hline
Type A & 10 & \checkmark & & \checkmark \\ \hline
Type B & 5 & \checkmark & & \\ \hline
Type C & 3 & & \checkmark & \checkmark \\ \hline
\end{tabular}
% no use \centering\hspace{\fill}
\end{document}
答案2
删除最后一p列以获得右侧的双垂直线。您正在加载makecell包，因此使用其\makecell宏将标题左对齐。此外，当您使用时arraybackslash，您可以\\在行尾使用。
\documentclass{amsart}
\usepackage{adjustbox}
\usepackage{mathtools}
\usepackage{makecell}
\usepackage{array}
\begin{document}
\noindent \hspace*{\fill}
\setlength\extrarowheight{2pt}
\begin{tabular}{|| c | >{\centering\arraybackslash}p{1.5cm} | >{\centering\arraybackslash}p{2.5cm} | >{\centering\arraybackslash}p{2cm} | >{\centering\arraybackslash}p{2cm} ||} \hline
\multicolumn{5}{|| l ||}{\textbf{Inventory of Clocks and Frequency of Chimes}} \\ \Xhline{0.8pt}
& \makecell[|l]{Number \\ of clocks}& \makecell[|l]{Chimes $n$ times \\ on the $n^{\mathrm{th}}$ hour \\and here} & \makecell[|l]{Chimes once \\ on the hour} & \makecell[|l]{Chimes once \\ on the \\ half-hour} \\ \hline
Type A & 10 & \checkmark & & \checkmark \\ \hline
Type B & 5 & \checkmark & & \\ \hline
Type C & 3 & & \checkmark & \checkmark \\ \hline
\end{tabular}
\hspace{\fill}
\end{document}
