Tabulator between Acronym and full text

Question

Based on this post( List of Acronyms without line spacing), I want to create a list of appreciations. But the long text are not in the same column.

But this is not the result they have. I need the tabulator between the short and the longtext version (the red line).

This is my aacronym code:

\documentclass[a4paper,11pt]{article}
\usepackage[printonlyused,withpage]{acronym}
\usepackage{xpatch}
\makeatletter
\xpatchcmd{\AC@deflist}
  {\addtolength{\leftmargin}{\labelsep}}
  {\addtolength{\leftmargin}{\labelsep}\setlength{\itemsep}{0pt}}
  {}{}
\makeatother
\begin{document}
\pagenumbering{Roman}
\section*{Table of abbreciations}
\input{sources/abbreviations}
\pagenumbering{arabic}
Use of \ac{saas} , \ac{yum}, \ac{jar} and \ac{ear} - \ac{LONGEXP}
\end{document}

with these abbreviations.tex

\begin{acronym}[d]
\acro{yum}[yum]{yellowdog updater modified}
\acro{ear}[EAR]{Enterprise Application Archive}
\acro{war}[WAR]{Web Application Resource}
\acro{jar}[JAR]{Java Archive}
\acro{saas}[SaaS]{Software as a Service}
\acro{LONGEXP}[LONGEXP]{A long acronym to make the point}
Markup Language}
\end{acronym}

The Output resulting Table of abbreviations is shown here:

But I need this result (Image edited with paint):

can another package interfere with the acronym-package?

Answer 1

Use

\begin{acronym}[LONGEXP]
    \acro{yum}[yum]{yellowdog updater modified}
    \acro{ear}[EAR]{Enterprise Application Archive}
    \acro{war}[WAR]{Web Application Resource}
    \acro{jar}[JAR]{Java Archive}
    \acro{saas}[SaaS]{Software as a Service}
    \acro{LONGEXP}[LONGEXP]{A long acronym to make the point}   
\end{acronym}
