我只想创建一个这样的表
但没有行与行之间的线。我也不需要像这样的列与列之间的线
但在现有方法 CFNeT 多列下方，我需要一行不跨越整个表格。我的意思是该行必须适合内容。
答案1
\documentclass[11pt]{article}
\usepackage{graphicx}
\begin{document}
This a multirow and multicolumn table
\begin{tabular}{|c|c|c|}
\hline
a & b & g\\
\hline
b & c & h\\
\hline
g & v & a\\
\hline
\end{tabular}
\end{document}
代表|分隔单元格每个元素的垂直线，并且c是将单元格内容居中的选项（还有其他的，如r->右和l->左）。
最后\hline代表水平线。我希望我说得够清楚了。

您必须对百分比（最后一列）的每次更改至少编译两次（因为它使用eqparbox以获得适当的对齐）。
\documentclass{book}
\usepackage[
margin=1in,
landscape
]{geometry} % Just for this example
\usepackage{booktabs,collcell,eqparbox,makecell}
\begin{document}
\begin{table}

\newcommand{\pa}[1]{\eqmakebox[CFNetvsNeuMF][r]{#1}}% Percentage alignment
\newcommand{\hlc}{\textbf}% Highlight cell
\caption{Comparison results of different methods in terms of NDCG@10 and HR@10.}
