我需要将下面的表格转换为长表。我查看了本网站中与此问题相关的其他主题。我删除了\begin{table}和\end{table}标签，还将所有标签替换为\begin{tabular}和\begin{longtable}。但它仍然不起作用。如果有人能帮助我将不胜感激...\end{tabular}\end{longtable}
我正在将原始表格复制到这里。

附录: 顺便说一下，不是有必要将每个单元格都包裹在\multicolumn{..}{...}包装器中。事实上，如果您避免这种做法，代码的可读性将大大提高。另外，与环境[c]的默认位置一样tabular，您不需要指定它。此外，我将定义一个宏（\mytab在下面的代码中调用）来简化输入所有\begin{tabular} ... \end{tabular}代码块（其中有二十多个）。最后，由于您交替使用浅灰色和白色行颜色，因此指令\cline不会做太多事情——我会完全省略它们。我也会省略所有内部垂直条；相信我，它们不会被遗漏。
