Latex表中缺少行

Question

我用latex做了一个表格，格式如下，

\begin{table}[H]
\centering
\begin{tabular}{|p{3.5cm}|l|l|l|l|l|l|l|p{1.0cm}|}
\hline
&\multicolumn{7}{c|}{Different values of K}\\
\cline{2-8}
1 & 3 & 4 & 5 & 6 & 7 &  8 & 9 & sum\\
\hline 
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\
\hline
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\
\hline
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\
\hline
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\
\hline
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\
\hline
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\
\hline
\end{tabular}
\caption {sum}
\label{tab:sum}
\end{table}

然而，当我运行它时，在右上角的表格上缺少一行。有人能帮我解决这个问题吗？我不能解决它。我正在使用在线latex。谢谢。

Answer 1

只需在该行末尾添加一个"&“即可：&\multicolumn{7}{c|}{Different values of K} &\\

Answer 2

 \begin{table}[h]
 \centering
 \begin{tabular}{|p{3.5cm}|l|l|l|l|l|l|l|p{1.0cm}|}
 \hline

 \cline{2-8}
  1 & 3 & 4 & 5 & 6 & 7 &  8 & 9 & sum\\ \hline 
   1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\ \hline
 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\ \hline
  1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\\hline 
   1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\\hline
  1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\ \hline

 \end{tabular}
 \caption {sum}
 \label{tab:sum}
  \end{table}
  % Here is the corrected version. You need to replace H by h and 
 %after    sum put & sign
