I have looked through so many tutorials regarding tables, vertical alignment, tried to do it on my own, tried to do it with excel2latex Excel addin - still having troubles with my table. I would really appreciate your help.
\begin{table}[htbp]
\centering
\caption{Add caption}
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|}
\toprule
\multirow{2}[4]{*}{long text} & \multirow{2}[4]{*}{text} &
\multirow{2}[4] {*}{\begin{sideways}text\end{sideways}} &
\multirow{2}[4] {*}{\begin{sideways}vertical long text\end{sideways}} &
\multicolumn{6}{c|}{long text} \\
\cmidrule{5-10} & & & & 1 & 2 & 3 & 4 & 5 & 6 \\
\midrule
... & ... & ... & ... & ... & ... & ... & ... & ... & ... \\
... & ... & ... & ... & ... & ... & ... & ... & ... & ... \\
... & ... & ... & ... & ... & ... & ... & ... & ... & ... \\

... & ... & ... & ... & ... & ... & ... & ... & ... & ... \\
... & ... & ... & ... & ... & ... & ... & ... & ... & ... \\
\midrule
\multicolumn{10}{|c|}{long long note)} \\
\bottomrule
\end{tabular}
\label{tab:addlabel}
\end{table}
The table should look like this

But instead it comes out like this
Please help me solve this mystery!




booktabsdoesn't work well with vertical rules (see the manual). Use the standard\hlineand\clineinstead. – Torbjørn T. Jul 29 '16 at 08:40
