        \end{tabular}
        \caption{First subtable1}\label{tab:sub_first1}
    \end{subtable}
    \caption{Three simple tables} \label{tab:three_tables}
\end{table*}

\end{document}

The resulting table is as follows:

Since I wanted the column 7 to be wider, I used p{<width>} argument. However, all the text in rest of the cells are now vertically top-aligned now.

So,

1. Is it possible to vertically center-align them?

2. The column header "Column 7" should be horizontally center-aligned. Is there a way to apply only to that cell?

Answer 1

1. using m{...} instead of p{} will centre align your cells

2. to center align the last column header: \multicolumn{1}{c|}{\multirow{2}{*}{\textbf{Column 7}}}
