最后一列垂直线缺失

我正在处理强大的tabularx环境。除了最后一列，我能够获得一个不错的表格。我总共需要七列，但最后我得到了另一半列。我不明白为什么！

这是我用于构建表的代码：

\begin{table}[h!]
 \begin{tabularx}{\textwidth}{|l|*{20}{>{\arraybackslash}X|}}

\multicolumn{1}{c}{}& \multicolthead{3}{\color{RoyalBlue}\textbf{I}}& \multicolthead{3}{\color{RoyalBlue}\textbf{II}} & \multicolthead{3}{\color{RoyalBlue}\textbf{III}} & \multicolthead{3}{\color{RoyalBlue}\textbf{IV}} & \multicolthead{3}{\color{RoyalBlue}\textbf{V}} & \multicolthead{3}{\color{RoyalBlue}\textbf{VI}} \\

\hline

\thead{\color{RoyalBlue}One\\\color{RoyalBlue} Time} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} \\

\hline

\thead{\color{RoyalBlue}Two\\\color{RoyalBlue} Times} & & & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & & & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \\

\hline

\thead{\color{RoyalBlue}Three\\\color{RoyalBlue}Times} & \multicolumn{3}{l|}{} & & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & & & \multicolumn{3}{l|}{} \\ 

\hline

\thead{\color{RoyalBlue}Four\\\color{RoyalBlue} \& Times} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & & \\

\hline

\end{tabularx}
\caption{{Caption}}
\end{table}

输出结果如下：

最后一列问题

有人有想法吗？

答案1

对于有垂直规则的列，您需要提供足够的&s 以便实际设置单元格。您缺少 last-column&来“输入”最后一列，导致右侧垂直规则缺失。

为了删除看似不合时宜的最后一列，您只需要 18 列，但您在tabular序言中建议 20 列。以下是更正后的内容：

在此处输入图片描述

\documentclass{article}

\usepackage{tabularx,colortbl}
\usepackage[dvipsnames]{xcolor}
\newcommand{\thead}[1]{\begin{tabular}{@{}c@{}}#1\end{tabular}}
\newcommand{\multicolthead}[2]{\multicolumn{#1}{@{}c@{}}{\thead{#2}}}

\begin{document}

\noindent
\begin{tabularx}{\textwidth}{|l|*{18}{>{\arraybackslash}X|}}
  \multicolumn{1}{c}{}& \multicolthead{3}{\color{RoyalBlue}\textbf{I}}& \multicolthead{3}{\color{RoyalBlue}\textbf{II}} & \multicolthead{3}{\color{RoyalBlue}\textbf{III}} & \multicolthead{3}{\color{RoyalBlue}\textbf{IV}} & \multicolthead{3}{\color{RoyalBlue}\textbf{V}} & \multicolthead{3}{\color{RoyalBlue}\textbf{VI}} \\
  \hline
  \thead{\color{RoyalBlue}One\\\color{RoyalBlue} Time} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} \\
  \hline
  \thead{\color{RoyalBlue}Two\\\color{RoyalBlue} Times} & & & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & & & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} \\

  \hline
  \thead{\color{RoyalBlue}Four\\\color{RoyalBlue} \& Times} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & \multicolumn{3}{l|}{} & & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & \cellcolor[HTML]{D3D3D3} & & \\
  \hline
\end{tabularx}
