![嵌套表格对齐问题](https://linux22.com/image/376550/%E5%B5%8C%E5%A5%97%E8%A1%A8%E6%A0%BC%E5%AF%B9%E9%BD%90%E9%97%AE%E9%A2%98.png)
下列的这例如,我尝试稍微扩展一下。
\begin{table}
\centering
\begin{tabular}{ |c|c|@{}c@{}| }% <-- aded @{}
\hline
no test & no test & \begin{tabular}{c|c|c} 1 & 2 & 3 \\ \hline 4 & 5 & 6 \\ \end{tabular} \\
\hline
no test & no test &
\begin{tabular}{c|c|c} D1 & 1.23 & 5 \\ \hline D2 & 1.23 & 6 \\ \end{tabular} \\
\hline
\end{tabular}
\end{table}
我懂了:
@{}c@{}
我在第三列中使用。为什么我有两种不同的嵌套表外观?
