为什么使用多列时会缺少行？

健康和总体列之间缺少线条

你观察到，

健康和总体列之间缺少线条

您必须更换

\multicolumn{2}{c}{BMI}

和

\multicolumn{2}{c|}{BMI}

附录：您的代码中有很多垃圾；更糟糕的是，表格的可读性并不好。\begin{tabular}{|c|c|cc|c|c|}由于表格包含 5 列而不是 6 列，因此您无法给人信心。看看我如何尝试解决下面第一个表格中最紧迫的问题。就我个人而言，我不能说我发现这个表格很有吸引力。第二个表格取消了所有垂直线，并使用左对齐而不是文本列居中。

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{multirow,makecell}

%% for the second table:
\usepackage{booktabs,siunitx}
\usepackage[skip=0.333\baselineskip]{caption}

\begin{document}
\begin{table}
\centering
\caption{Dreadful}
\begin{tabular}{|c|c|cc|c|} 
\hline
\multirow{2}{*}{Activity level} & 
\multirow{2}{*}{Resting heart rate} & 
\multicolumn{2}{c|}{BMI} & 
\multirow{2}{*}{Total}\\ 
& & Unhealthy & Healthy &  \\
\hline
Inactive & Normal   & 9  & 13 & 22\\ 
         & Abnormal & 16 & \cellcolor{pink}8 & 24\\
Active   & Normal   & 3  & 28 & 31 \\ 
         & Abnormal & \cellcolor{gray}6 & \cellcolor{gray}17 & 23 \\ 
\hline
Total    &          & 34 & 56 & \textbf{100} \\
