如何更正表格的标记?

如何更正表格的标记?

请帮帮我,如何才能更正表格的标记。我尝试这样做,但出现错误:

! LaTeX Error: Illegal character in array arg.

我猜测,发生此错误是因为我没有为 \tabular 命令提供任何参数。我尝试提供一、二、三和四个参数,但此错误并未消失。使用 \message 命令时,我注意到,我为命令提供的每个参数,使用 \cs_gset_protected:cpn{tabular}#1 #2 #3 #4{\some_code} 为命令 tabular 的每个参数仅提供一个字符。例如,对于 \tabular{ccc},我为每个参数提供类似 { ccc} 的内容。请帮帮我修复此错误。还请帮帮我,对于表格、制表符和任何其他表格环境、每行和单元格,我应该使用什么命令。如果我知道这些命令,我​​将自己标记这些环境。非常感谢您帮助修复错误并提供表格环境命令。

这里的意图并不完全清楚,但错误是因为您\orig@tabular在定义中间调用,所以它的参数是以下标记(\let)而不是{cc}来自文档的标记。

在这种情况下,所有以下标记都是与tabbing不相关的内部命令的重新定义,tabular所以我只是删除了它们,它可以运行,但会出现一些有关标签结构的警告。

\usepackage{tagpdf}
\tagpdfsetup{tabsorder=structure,uncompress,activate-all,add-new-tag=Title/P,interwordspace=true}
\ExplSyntaxOn

\cs_set_eq:NN\orig@tabular\tabular
\cs_set_eq:NN\orig@endtabular\endtabular
\cs_gset_protected:Npn\tabular{
\cs_new_protected:Npn \l__tab_char: {
