I'm trying to make a table that's a little complex. I'll try to explain what I want with a picture of a table from word:

I'm new to latex, so I have two questions. How can I make such table look good? And secondly - how do I make it in LaTex? I've tried the following:

```
\begin{table}[hbr]
\caption{Description}
\label{tbl:hexhcomp}
\centering
\noindent
\def\arraystretch{1.2} 
\begin{tabular}[c]{|l || c| c| c| c| c| c| c| c|}
  \cline{2-7}
  \multicolumn{1}{c|}{} &
    \parbox[t]{0.8cm}{\rotatebox[origin=c]{90}{\textbf{Thermal\\wheel}}} &
    \parbox[t]{0.8cm}{\rotatebox[origin=c]{90}{\textbf{Energy\\wheel}}} &
    \parbox[t]{0.8cm}{\rotatebox[origin=c]{90}{\textbf{Fixed\\matrix}}} &
    \parbox[t]{0.8cm}{\rotatebox[origin=c]{90}{\textbf{Plate}}} &
    \parbox[t]{0.8cm}{\rotatebox[origin=c]{90}{\textbf{Tube}}} &
    \parbox[t]{0.8cm}{\rotatebox[origin=c]{90}{\textbf{Run-around}}} &
    \parbox[t]{0.8cm}{\rotatebox[origin=c]{90}{\textbf{Heat- pipe}}} &
    \parbox[t]{0.8cm}{\rotatebox[origin=c]{90}{\textbf{Membrane}}} \\[15pt]
  \hline
  \hline

  \parbox[t]{3cm}{\raggedright{Sensible efficiency}} & N & N & N & Y & Y & Y & Y & Y \\[15pt]
  \hline
  \parbox[t]{3cm}{\raggedright{Latent efficiency}} & N & N & N & N & Y & Y & Y & Y \\[15pt]
  \hline
\end{tabular}
\end{table}

```

Is there a simpler or more elegant way of achieving this?
