我正在尝试加宽标题为“应用程序”的列，以便表格整体变矮，而且尽管在 {table*} 命令旁边放置了 h、t、b、! 等参数，我也在更改表格显示位置时遇到了麻烦（现在它总是出现在下一页）。以下是代码：
\setlength{\extrarowheight}{4pt}
\begin{table*}[h!]
\caption{COMPARISON OF SUITABILITY OF SELECT ESS TO PROVIDE SHORT TERM GRID FUNCTIONS}
\label{my-label}
\begin{threeparttable}
\begin{tabularx}{\textwidth}{@{}l*{20}{C}c@{}}
\toprule
\multirow{Service Category} & \multirow{Application} & \multirow{Discharge Duration} & \multicolumn{5}{c}{Energy Storage System} \\
[-\normalbaselineskip]
\cmidrule{4-8}
{} & {} & {} & Sodium-sulfur Battery & Lithium-ion Battery & Flywheel & SMES & Supercapacitors \\

\bottomrule
\end{tabularx}
\begin{tablenotes}
\item[1] Proposed
\item[2] Proposed
\end{tablenotes}
\end{threeparttable}
\end{table*}
这是现在的表格
非常感谢大家的帮助！

看看下面的表格设计是否可以接受：
\documentclass[twocolumn]{article}
\usepackage{booktabs, makecell, multirow, tabularx, threeparttable}
\newcolumntype{C}[1]{>{\centering\arraybackslash\hsize=#1\hsize}X}
\newcolumntype{L}[1]{>{\raggedright\arraybackslash\hsize=#1\hsize}X}
\usepackage[skip=1ex, font=sc]{caption}
\usepackage[version=4]{mhchem}
\usepackage{siunitx}
