我想创建多行表。这是基线表。

\section{Introduction}
\begin{table}[!t]

输出为
现在我想将workload列分成两列。像这样
+-----------------+----
| workload
+----------+-----------
| | A
| | D
| group1 | G
| | J
| | M
| | P
-----------------------
-----------------------
| | S
| | V
| group2 | Y
| | AB
| | AE
| | AH
-----------------------
-----------------------
| | AK
| group3 | AN
-----------------------
因此，我在表格行上添加了另一列，将 6{}p 增加到 7p{}，并添加了以下几行
\multirow{6}{*}{group1} & A & B & C & 1 & 2 & 3 \\
...
\multirow{6}{*}{group2} & S & T & U & 19 & 20 & 21 \\
...
\multirow{2}{*}{group3} & AK & AL & AM & 36 & 37 & 38 \\
但结果却远远超出了预期。事实上，我没有看到任何行跨度！！
更新
应用答案中的方法并将 A、B、... 替换为真实文本后，我看到此输出
\addlinespace我使用了而不是\hline。如您所见，每组中的行之间都有间隙。
答案1
应该使用水平线来构造内容，但右侧的空白也可以起到同样的作用。看看表格，它看起来更干净。请注意规则前后的小空白。
这个包siunitx帮助我们将数字按小数点对齐。

我不太确定我是否理解了这个问题。我尝试构建一个场景，但没有成功。目前我无法重现这种行为。请注意，这multirow总是需要手工劳动。请注意，我使用\midrule了再次以获得更好的间距。
请考虑以下事项
