Hi David, Alain, and others,

There is also:
d) the initial  {\footnotesize .... } wrapping around the whole
tabular, reducing the overall fontsize and baseline skip;
which reduces the amount of space *between* cells in a row.

Of course it is unclear from the original poster's example
what form the data will come in --- presumably numbers,
but with how many digits, and what kind of alignment?
This may affect the widths of columns. In my example code
the header cells dictate the widths, choosing between 3 fixed
amounts which were designed to accommodate the headers.

It may well be that in practice the data dominates in some columns,
which will then affect the overall width of the table.

Sure; that's certainly a good package to use.

If it was for *recording* data manually, then yes, the small
font-size is not a good idea at all.
I'd assumed that he wants to display data already collected,
or to be collected in future.

With data in a speadsheet, it is easy to add extra columns
in-between, filled-down with &s and \\ at the end of each row.
Then a copy/paste into the LaTeX source can provide the data
cells to populate the {tabular}.

Certainly using landscape orientation is an option;
e.g. with a \rotatebox{90}{....} command.
But if you do this, it would be best done within a float,
probably on a page by itself.
It also can help in positioning the \caption to use a
{minipage} environment, estimating the actual width
(which becomes height) required; e.g.,

\begin{table}[p]
\centering
\rotatebox{90}{%
\begin{minipage}{1.2\textwidth}
\caption{....}
\medskip
\begin{tabular}{....}
...
...
\end{tabular}
\end{minipage}
}%  end of \rotatebox
\end{table}

Of course there are packages which provide alternative commands
to do some of these things with different markup.
What is important is understanding how the markup relates
to geometrical concepts, and nesting them correctly so that
the coding processes smoothly.

Sure. But it doesn't take much to use this for data,
and employ LaTeX for a high-quality, aesthetic layout.

Hope this helps,
