我是 LaTeX 新手。因此，我应该创建一个表格，代码如下：
\usepackage{booktabs}
\usepackage{multirow}
\usepackage{graphicx}
\begin{table}[]
\centering
\resizebox{\textwidth}{!}{%
\begin{tabular}{@{}|c|l|c|@{}}
\toprule
\multicolumn{2}{|c|}{\textbf{Cortex A9 Parameters}} & \textbf{Values} \\ \midrule
\multicolumn{2}{|c|}{\textbf{Core clock}} & 800 MHz \\ \midrule
\multirow{5}{*}{\textbf{L2}} & \textbf{Size} & 512 kB \\ \cmidrule(l){2-3}
& \textbf{Associativity} & 8 \\ \cmidrule(l){2-3}
& \textbf{Latency} & 8 \\ \cmidrule(l){2-3}
& \textbf{MSHRs} & 11 \\ \cmidrule(l){2-3}
& \textbf{Write buffers} & 9 \\ \midrule
\multirow{4}{*}{\textbf{L1 - I}} & \textbf{Size} & 32 kB \\ \cmidrule(l){2-3}

\end{tabular}%
}
\caption{My caption}
\label{my-label}
\end{table}
但我一直得到像这样的表格：
它很大，但我可以接受这个尺寸，但边框不太好。
有人可以帮忙吗？

一种“经典”的表格设计，使用\hline替代\booktabs规则，单元格中的垂直空间增加了\renewcommand\arraystretch{1.2}（如果您希望拥有更多的垂直空间，请增加\arraystretch），并通过使用两个新命令和定义的列来使用字体，使代码尽可能简单和简洁\bfseries：
\documentclass{article}
% \usepackage[showframe]{geometry}
\usepackage{array,multirow}
\newcommand\mcbf[1]{\multicolumn{2}{|c|}{\textbf{#1}}}
\newcommand\mlbf[1]{\multicolumn{2}{|l|}{\textbf{#1}}}
\usepackage{graphicx}
\begin{document}
\begin{table}[htb]
\centering
\renewcommand\arraystretch{1.2}
\begin{tabular}{|>{\bfseries}c|>{\bfseries}l|c|}
\hline
\mcbf{Cortex A9 Parameters} & \textbf{Values} \\ \hline
\mcbf{Core clock} & 800 MHz \\ \hline
\multirow{5}{*}{L2} & Size & 512 kB \\ \cline{2-3}
& Associativity & 8 \\ \cline{2-3}
& Latency & 8 \\ \cline{2-3}
& MSHRs & 11 \\ \cline{2-3}
& Write buffers & 9 \\ \hline
\multirow{4}{*}{L1 - I} & Size & 32 kB \\ \cline{2-3}
& Associativity & 4 \\ \cline{2-3}
& Latency & 1 \\ \cline{2-3}
& MSHRs & 2 \\ \hline
\multirow{5}{*}{L1 - D} & Size & 32 kB \\ \cline{2-3}
& Associativity & 4 \\ \cline{2-3}
& Latency & 1 \\ \cline{2-3}
& MSHRs & 4 \\ \cline{2-3}
& Write buffers & 16 \\ \hline
{Stride prefetcher} & Degree & 1 \\ \hline
\multirow{2}{*}{Global BP} & Entries & 4096 \\ \cline{2-3}
& Bits & 2 \\ \hline
\mlbf{BTB entries} & 4096 \\ \hline
\mlbf{Return Address Stack (RAS) entries} & 8 \\ \hline
\mlbf{Issues width} & 2 \\ \hline
\mlbf{Pipeline stages} & 8 \\ \hline
\mlbf{Physical INT registers} & 62 \\ \hline
\mlbf{Physical FP registers} & 256 \\ \hline
\mlbf{IQ entries} & 32 \\ \hline

\mlbf{ROB entries} & 40 \\ \hline

你不仅应该从表格中省略所有垂直规则（相信我，它们是不需要的，而且它们不会被遗漏……），你还应该摆脱全部水平线内部的表格。\cmidrule完全省略指令，并将所有内部实例替换为\midrule。\addlinespace你
此外，表格内容确实没必要加粗。事实上，从排版角度来说，您的读者可能会喜欢不被无休止的叫喊所攻击。

要么使用书形标签，要么使用垂直线，不能同时使用两者（并且永远不要缩放表格，如果需要更改大小，请使用特定大小，例如\small）

答案4
您的问题来自于在booktabs水平线周围添加垂直填充。我将此填充设置为 0pt，并将其替换为\makegapedcells 。makecell此外，我将\multirow 命令替换为\makecell，这允许在单元格中换行，并且我删除了许多水平规则。此外，您不应该将其用于\resizebox表格，它看起来很丑陋。在本例中，您不需要它来适应边距之间的表格。
以下是简化的代码：
