Answer 1

我怀疑以下内容可能就是您要找的内容。请注意，所有center环境都已被删除，\centering在最外层环境之前立即提供了一条指令tabular，提供了缺少的\begin{table}指令，并且外部环境中的列数tabular从 4 减少到 3。

\documentclass{article}
\usepackage{array} % for "\extrarowheight" macro
\usepackage[skip=0.333\baselineskip]{caption}
\begin{document}

\begin{table}
\setlength\extrarowheight{2pt} % for a slightly more open "look"
\centering
\caption{Nested \texttt{tabular} environments}
\begin{tabular}{|c|c|c|}
\hline
Type of Variation & C & B \\
\hline \hline
      SNP & 
      \begin{tabular}[t]{@{}cccc@{}} % "@{}" omits side padding
         1&2&3&4 \\ 
         A&C&G&T \\ 
         A&T&G&T \\
      \end{tabular} &
      \begin{tabular}[t]{@{}ccc@{}}
         POS & REF & ALT\\ 
         2   & C   & T  \\ 
      \end{tabular} \\ 
\hline
\end{tabular}
\end{table}

\end{document}
