# Text in rotated multirow cell crosses table border

I'm trying to create a table like this:

For it, I wrote the following code:

\begin{table}[h!]
\begin{tabular}{|c|c|c|}
\hline
\multicolumn{2}{|c|}{one}
& \multirow{2}{*}{\rotatebox{90}{one and a half~}} \\ \cline{1-2}
two & three & \\
\hline
\end{tabular}
\end{table}


However, the output is not quite as expected:

The best workaround for this I found so far was this answer: http://tex.stackexchange.com/a/74550/22718. But it seems a bit excessive, especially considering I need this layout in multiple places and for every column I would have to write something like \setbox0\hbox{\tabular{@{}l}Metszéspontok\\ Száma\endtabular}, if I understand correctly. Also, to my mind, it's pretty simple formatting, I achieved this in LO Calc with a few mouse clicks, so it should be not that difficult in LaTeX, right?

I would really appreciate any suggestions!

\documentclass{article}

\usepackage{graphicx}
\begin{document}

\begin{table}[htp!]
\begin{tabular}{|c|c|c|}
\hline
\multicolumn{2}{|c|}{one}
& \\ \cline{1-2}
two & three &
\rotatebox{90}{one and a half~\hspace{-\normalbaselineskip}}\\
\hline
\end{tabular}
\end{table}

\end{document}
