\end{document}

This table extends very close to the end of the right side of the page. How can I set the width of such a table?

You can set the widths of columns using p{2cm} as for a normal tabular. With longtable you don't explicitly set the total table width but you can set the left and right margin to set the width as shown in the longtable documentation

% Normally centring is the default, but this document specifies
% \DescribeMacro{\LTright}
%\begin{verbatim}
% \setlength\LTleft\parindent
% \setlength\LTright\fill
%\end{verbatim}
% in the preamble,
%  which means that the tables are set flush left, but
% indented by the usual paragraph indentation. Any lengths can be
% specified for these two parameters, but at least one of them should be
% a rubber length so that it fills up the width of the page, unless
% rubber lengths are added between the columns using the
% "\extracolsep" command.
% For instance
%\begin{verbatim}
%  \begin{tabular*}{\textwidth}{@{\extracolsep{...}}...}
%\end{verbatim}
% produces a full width table, to get a similar effect with
% \env{longtable} specify
%\begin{verbatim}
% \setlength\LTleft{0pt}
% \setlength\LTright{0pt}
% \begin{longtable}{@{\extracolsep{...}}...}
%\end{verbatim}
%

For your table I think you either need to make the font smaller or set it landscape so either

\begin{document}
\small
\setlength\tabcolsep{2pt}
\begin{longtable}[l]{ lllllllllllllllll }

or get the lscape package and

\begin{document}
\begin{landscape}
\begin{longtable}[l]{ lllllllllllllllll }
...
\end{longtable}
\end{landscape}

Or, if you don't want your document margins to be used as margins, you can steal the space from there:

\begin{document}
\setlength\LTleft{-1in}
\setlength\LTright{-1in plus 1 fill}
\begin{longtable}{ lllllllllllllllll }

[Tex/LaTex] Multicolumn width in longtable

You are lucky, because package longtable records the width of the columns in the .aux file. That can be used to calculate the width of the first two columns.

Macro \GetLongtableWidths extracts the widths of the next longtable. It is called just before \begin{longtable}. Inside the p specification \wdcal is used. The first argument is a minimal width that is used if the widths are not yet in the .aux file. This width should be smaller or at most equal to the final width. The second argument of \wdcal takes an expression. \wdcol<colnum> is replaced by the width of the column <colnum>. Because the column specification p{...} of \multicolumn does not suppress \tabcolsep (at the left and right of the column), two \tabcolsep needs to be subtracted.
