I'm getting some little problems when using \multirow:
Here is my code:
\documentclass[a4paper,10pt]{article} % Default font size and paper size \usepackage{multirow} \begin{document} \begin{tabular}{ |l| c| c| } \hline \textbf{1} & \textbf{2} & \textbf{3} \\ \hline \multirow{4}{*}{A} & 1 & 1 \\ & 2 & 2 \\ & 3 & 3 \\ \hline \multirow{4}{*}{B} & 1 & 1 \\ & 2 & 2 \\ \hline \end{tabular} \end{document} Here is the preview:

Problems:
- As you can see, in cell (2,1), the B is not properly positioned in the middle of the cell
- How is it possible to separate only multirows in Row 1?


\multirowis the number of rows spanned: it should be 3 in the first case, 2 in the second case. The second question is not clear.
