我需要将表格置于中央但我不得不使用以下宏：
\def\tbl#1#2#3{%
\global\setbox\tabcapbox\vbox{#1}%
\global\setbox\tabbox\hbox{#2}%
\global\setbox\tabnotebox\vbox{#3}%
\noindent\vbox{%
\tablemove\textwidth%
\advance\tablemove-\wd\tabbox%
\divide\tablemove2%
%\hspace*{\tablemove}
\vbox{%
\hsize\wd\tabbox%
#1%
#2%
#3}}}
宏不允许我将表格居中。我用过\centering，但不起作用（不是完全居中）。我makebox[\textwidth][c]{在表格周围使用了它，但没有完全居中。我需要在宏中进行哪些修改（或删除）才能使整个表格居中。
以下是整个代码片段：

\tbl 宏是期刊类。只需将 \documentclass{article} 更改为 \documentclass{Jclass}。您可能会遇到问题，因为该类与最近的 LaTeX 2e 内核不兼容，但可以按如下方式解决这里解释。
