Non sono ben sicura di cio’ che vuoi ottenere ma prova con

Preambolo
`\usepackage{multicol}`

Corpo del documento (es. 3 colonne):
`\begin{multicols}{3}
\begin{list}
…
\end{list}
\end{multicols}`

Io uso tikz cosi’ posso usare indifferentemente latex o pdflatex e posso inserire piccole immagini “in linea”.

Un esempio:

nel preambolo
`\usepackage{tikz}`

nel corpo del documento
`\begin{tabular}
\tikz{
\draw (0mm,10mm) — (20mm, 10mm);
\draw (10mm,10mm) circle (1mm);
\draw (12mm,12mm) node{a};
}
& il valore $a$ è escluso \\
\tikz{
\draw (0mm,10mm) — (20mm, 10mm);
\draw[fill] (10mm,10mm) circle (1mm);
\draw (12mm,12mm) node{a};
}
& il valore $a$ è incluso
\end{tabular} `

Temo d’aver capito male, dici di usare Latex->PDF (da cui deduco che usi PDFLatex) e quindi non generi alcun dvi. Altrimenti, se generi anche il dvi, significa che o fai “la catena” latex->dvips->ps2pdf oppure “la catena” latex->dvi2pdf.

Comunque, al posto di \usepackage[dvips]{graphicx} scrivi solo \usepackage{graphicx}.

Inoltre, se usi PDFLatex allora hai bisogno di immagini png oppure pdf oppure jpg, se usi latex->dvips->ps2pdf oppure latex->dvi2pdf le immagini devono essere in eps.

Non credo che possa fare danni, guarda tu stesso il .sty:

% This is free, unencumbered, unsupported software.

% Commands defined are:
% \bra{ } \ket{ } \braket{ } \set{ } (small versions)
% \Bra{ } \Ket{ } \Braket{ } \Set{ } (expanding versions)
%
% The “small versions” use fixed-size brackets independent of their
% contents, whereas the “expanding versions” make the brackets and
% vertical lines expand to envelop their contents (internally using
% the \left and \right commands). You should use the vertical bar
% character “|” to input any extra vertical lines. In \Braket these
% vertical lines will expand to match the arguments, and in \Set the
% first vertical will expand. E.g.,
%
% \Braket{ \phi | \frac{\partial^2}{\partial t^2} | \psi }
% \Set{ x\in\mathbf{R}^2 | 0<{|x|}<5 } % % Likewise, you may make an expandable double-bar using either % the "\|" command or its local alias "||". % % NOT defined is "\ketbra" (for projection operators) because I prefer % \ket{ } \bra{ }. % % Because each definition is so small, it makes no sense to have a % complicated generic version for many bracket styles. Instead, % you can just copy the definitions and change \langle or \rangle, % < and > to what you like.

Forse il pacchetto “textpos” ti puo aiutare.

Non so se funzionano insieme ma puoi provare a mettere la longtable in un ambiente landscape del pacchetto lscape.

Forse ti sbagli. Se usi le lettere la classe koma agginunge il prefisso cioè la parola capitolo o appendice, non il punto

Forse ho capito male io ma a pag. 57 della doc inglese c’è scritto:

pointednumbers
pointlessnumbers
According to DUDEN, the numbering of sectional units should have no
point at the end if only arabic numbers are used (see [DUD96, R 3]).
On the other hand, if roman numerals or letters are used, then a point
should appear at the end of the numbering (see [DUD96, R 4]). KOMAScript
has an internal mechanisms that tries to implement these rules. The
resulting effect is that, normally, after the sectional commands \part and
\appendix a switch is made to numbering with a point at the end. The
information is saved in the aux file and takes effect on the next LATEX run.
In some cases the mechanism that switches the end point may fail or
other languagues may have different rules. Therefore it is possible to
activate the use of the end point with the option pointednumbers or
to deactivate it with pointlessnumbers.
Please note that the mechanism only takes effect on the next LATEX
run. When trying to use these options to control the numbering format,
a run without changing any options should be made.
Calling these options dottednumbers and dotlessnumbers or similar
would be more correct. It so happened that the meaning of the chosen
names was not clear to me a few years ago when the options were implemented.
