我无法垂直对齐第一列。您能建议其他方法让此表格看起来更美观吗？我将不胜感激。

编辑：
- 您的表格代码没有必要那么复杂。由于所有列的宽度都相等，因此您可以省略所有宽度设置。
- 内部列的使用
\parbox不一致且没有必要 - 如果您希望在内容为列表的情况下使用不同的列宽（
itemize），则需要按如下方式重新定义它们的宽度：{\hsize=#1\hsize\linewidth=\hsize}或者为了更方便地编写列规范，如上面的 MWE 中所示 - 从文档序言中删除所有重复项
附录 您的表格可以放在一列中。为此，我建议
- 减小尺寸
\tabcolsep（从默认的 6pt 减小到例如 4pt） - 减小字体大小至
\small @{}通过在列规范的开始和结束处插入来删除表中的第一个和最后一个空格- 第一列替换为行
