如何在表格的多行环境中对齐单元格条目？

我正在尝试在多行环境中编写表格。但是，我的条目没有正确对齐。代码粘贴在下面。输出的屏幕截图已附上。有人能帮我解决这个问题吗？非常感谢。

答案1

缺少第二行（&需要两行），因此内容对齐不正确。

*我在命令的第二个参数中添加了\multirow并更正了表格行的结尾（\\）。

所结果的平均能量损失（请注意，它是最小的，我已经减少了它）：

\documentclass[sigconf, authordraft]{acmart}

\usepackage{booktabs}
\usepackage{multirow}

\begin{document}
\begin{table}
\centering
\caption{Quality Metrics which require reference image}
\label{tab:table1}
\begin{tabular}{cccccccccl}
Sl.No. & Metric & Band & DWT -rule 1 & DWT -rule 2 & DWT -rule 3 & DWT-rule 4 & PCA & GIHS & GIHS-Choi  \\
\midrule
\multirow{4}{*}{1} & \multirow{4}{*}{Rel Bias} & Green & DWT-rule1 & DWT-rule2 & DWT-rule3 & DWT-rule4 & PCA & GIHS & GIHS-Choi \\
 & & Green& DWT-rule1 & DWT-rule2& DWT-rule3 & DWT-rule4& PCA&GIHS&GIHS-Choi \\
 & & Green& DWT-rule1 & DWT-rule2& DWT-rule3 & DWT-rule4& PCA&GIHS&GIHS-Choi \\
 & & Green& DWT-rule1 & DWT-rule2& DWT-rule3 & DWT-rule4& PCA&GIHS&GIHS-Choi \\
\bottomrule
\end{tabular}
\end{table}
\end{document}

其结果是： enter image description here

&除了在数据行 2-4、6-8 和 10-12 中插入缺失符号外，您可能还想重新考虑表格的布局。例如，不要使用\multirow特殊方式处理前两列的内容，只需删除\multirow包装器并在第 4 行和第 8 行后添加一些垂直空白（通过\addlinespace说明）。此外，考虑到表格几乎占据了文本块的整个宽度，为什么不“将其正式化”并使用确实tabular*占用全部可用空间的环境呢？
