表的第一行出現此錯誤：
> ! Extra }, or forgotten $.<template> \unskip \hfil }\hskip \tabcolsep
> \endtemplate 1 & ! Missing $ inserted.<inserted text>$ 1 & !
> Missing } inserted.<inserted text>} 1 & ! Extra alignment tab has been

這僅在添加表的第五列後發生

如何管理我在評論中描述的錯誤。在這裡我想展示我將如何編寫你的表：
- 新增包
siunitx以更好更簡單地設定第三個表的列 - 加上
booktabs水平規則的包（你是人的對面站點的極端，所有行都用 分隔\hline，你沒有人:-)）
