我一直在尝试在乳胶代码中插入天线尺寸表。我使用了代码
\begin{table}[h]
\centering
\begin{tabular}{l | l | l | l | l}
Reference Number & BW (GhHz) & Antenna size (mm3) & Gain & Notched Bands (GHz) \\
\hline
[20] & 2.3-13.75 & 39*39*1 pt 6 & 1 pt 4-46 & 2 pt 25-3.75
5.08-5.9
7.06-7.95
\\
[21] & 3.11-13.15 & 28*52*1.6 & 1.53-4.05 & 5.1-5.92 \\
[22] & 2.8-14 & 27*36*1.6 & N/A & 3.26-3.9
4.35-5.05
5.5-6.35
7.95-9.35
\\
Current Work & 3.1 – 17 & 24*28*1.6 & 4.5-8 & 3.2-3.9
7.2-8.5
\end{tabular}
\caption{Comparison of the suggested antenna to antennas in previous litrature}
\end{table}
\end{document}
但错误：
\begin{table}[h]
\centering
\begin{tabular}{l | l | l | l | l}
Reference Number & BW (GhHz) & Antenna size (mm3) & Gain & Notched Bands (GHz) \\
\hline
[20] & 2.3-13.75 & 39*39*1 pt 6 & 1 pt 4-46 & 2 pt 25-3.75
5.08-5.9
7.06-7.95
\\
[21] & 3.11-13.15 & 28*52*1.6 & 1.53-4.05 & 5.1-5.92 \\
[22] & 2.8-14 & 27*36*1.6 & N/A & 3.26-3.9
4.35-5.05
5.5-6.35
7.95-9.35
\\
Current Work & 3.1 – 17 & 24*28*1.6 & 4.5-8 & 3.2-3.9
7.2-8.5
\end{tabular}
\caption{Comparison of the suggested antenna to antennas in previous litrature}
\end{table}
\end{document}
一直显示。我怎样才能简单地在表中插入项目的尺寸。

看看您的表格中的以下 MWE 是否可以接受：
\documentclass{article}
\usepackage{makecell}
\setlength\extrarowheight{2pt}
\begin{document}
\begin{table}[ht]
\centering
\begin{tabular}[t]{l | l | l | l | >{\raggedright\arraybackslash}p{9em}}
\hline
\makecell{Reference\\ Number}
& \makecell{BW\\(GHz)}
& \makecell{Antenna\\ size (mm)}
& \makecell{Gain\\ (dB)}
& \makecell{Notched\\ Bands (GHz)} \\
\hline
{[20]} & 2.3-13.75 & 39*39*1 & 4-46 & 25-3.75 5.08-5.9 7.06-7.95 \\
