我正在尝试在两列页面中将两个表格并排放置，我正在使用此示例
1但桌子是这样的
如何制作成这样的图片
\begin{table}[!htb]
\floatsetup{floatrowsep=qquad, captionskip=4pt}
\begin{floatrow}[2]
\makegapedcells
\ttabbox%
{\begin{tabularx}{0.45\textwidth}{|c| *{2}{>{\centering\arraybackslash}X|}}
\hline

其次，我正在使用此示例制作一个表格，但是它变得相当大，我尝试使用 \scalebox{0.5}，但是它不起作用。
我怎样才能使这张桌子变小？
