[Tex/LaTex] How to fit landscape multi-page table to textwidth

landscapelongtablemargins

\usepackage{longtable}

\begin{landscape}
\begin{table}[!htb]
\centering
\resizebox{\linewidth}{!}{%
\begin{longtable}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}

% Table here

\end{longtable}%
}%
\end{table}
\end{landscape}

I am unable to get the table to span over multiple pages while fitting the table to the width of the landscape page.
Would you know how to do this, please let me know.

First off, don't use both table and longtable -- the two environments shouldn't (and mustn't) be nested. Separately, since a longtable isn't a float (in the LaTeX sense of the word), there's no point providing location directives such as [!htb].

Second, to force the width of the longtable environment to be equal to \textwidth, type something like

\usepackage{longtable,lscape}
...
\begin{document}
...
\begin{landscape}
\setlength\LTcapwidth{\textwidth} % default: 4in (rather less than \textwidth...)
\setlength\LTleft{0pt}            % default: \parindent
\setlength\LTright{0pt}           % default: \fill
\begin{longtable}{@{\extracolsep{\fill}}|*{15}{c|}}
... % tabular material here
\end{longtable}
\end{landscape}
...

Note that the code above also resets the \LTcapwidth macro; since you're working in landscape mode, you'll almost certainly want to override this macro's default value of 4 inches. The @{\extracolsep{\fill}} directive, by the way, is exactly the same as what one would use in a tabular* environment. It tells LaTeX to insert \fill -- an infinitely stretchable amount of whitespace -- in each intercolumn space.

For more information on using the longtable environment, see the longtable user guide; if you're using TeXLive or MikTeX, the user guide may be brought up by typing texdoc longtable in a command window.
