Prevent word wrap and new lines in table cells

Question

I have a xltabular table which is filled via script with data, so I don't really know what length the text has that is put into the table cells. Is there a function or method which can just cut off the text if it is too long to fit in one line? Here is the example of my table.

\documentclass[
fontsize=11pt,
parskip=half,
firstfoot=off,
foldmarks=off
]{scrlttr2}  
%

\usepackage[T1]{fontenc} 
\usepackage[ngerman]{babel} 
\usepackage{lmodern}  

\usepackage{xltabular}
\usepackage[textwidth=\useplength{firstfootwidth}]{geometry} %showframe
               
\renewcommand*\familydefault{\sfdefault}    




\begin{document} 

%recipient  
\begin{letter}{ 
Max Muste \\
Teststraße 2    \\
55555 Teststadt \\
Schweiz         \\ 
     }
% 
\opening{}
%
    
{\footnotesize
\begin{xltabular}{\textwidth}{@{\hskip0pt}r p{3.1cm} X r r r@{\hskip0pt}}

Menge & Artikelnummer & Bezeichnung & WHG & Einzelpreis & Gesamtpreis \\ \hline 
\endfirsthead

Menge & Artikelnummer & Bezeichnung & WHG & Einzelpreis & Gesamtpreis \\ \hline 
\endhead
\hline
\multicolumn{6}{l}{Bla}
\endlastfoot

\end{xltabular}
}

\end{letter} 
\end{document} 

So basically mm, 12,5g should be thrown away, even if it is as text in the cell.

Answer 1

Well, there is not much sense to use an X column if you want to do that, an l ones will work ok, but one option is to use the truncate package (although you need a bit of gimmick to automatically apply it to a cell, here I use collcell package):

\documentclass[
fontsize=11pt,
parskip=half,
firstfoot=off,
foldmarks=off
]{scrlttr2}
%

\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
\usepackage{lmodern}

\usepackage{xltabular}
\usepackage[textwidth=\useplength{firstfootwidth}]{geometry} %showframe
\usepackage[fit, hyphenate]{truncate}
\usepackage{collcell}
\def\mytruncate{\truncate{6cm}}
\newcolumntype{T}{ >{\collectcell\mytruncate}X<{\endcollectcell} }

\renewcommand*\familydefault{\sfdefault}
\begin{document}

%recipient
\begin{letter}{
Max Muste \\
Teststraße 2    \\
55555 Teststadt \\
Schweiz         \\
     }

\opening{}
