Vertical Alignment in multirow using cells with >1 lines

From my experience multirow is not capable of a correct vertical alignment, if it spans multi-line cells. You can, however, adjust the alignment manually using the fixup-parameter:

% \multirow{nrows}[bigstruts]{width}[fixup]{text}
\multirow{-10}{*}[3em]{\cellcolor{yellow}\begin{sideways}TEST\end{sideways}}

Other possibilities for solving this problem are discussed in "Centering mutirow text in a table whose cells contain several lines of text" and "How can I achieve proper vertical spacing for long blocks of text within a \multirow?".

This table is easy and straight forward to produce using cals. Nothing special, only standard commands:

\documentclass[a4paper, 11pt]{article}
\usepackage{cals, xcolor, rotating}
\usepackage[margin=2.5cm]{geometry}


\let\nc=\nullcell                                                  % Shortcuts
\let\sc=\spancontent
