Csvsimple \csvautotabular and \csvautobooktabular with centered columns' content

As far as I can see, there's no provision for changing the column alignment in \csvautotabular; you can generate a different command by mimicking what csvsimple does for the stock command:

\documentclass[11pt,a4paper]{memoir}

\usepackage{csvsimple} % For csv importing.

\makeatletter
\csvset{
  autotabularcenter/.style={
    file=#1,
    after head=\csv@pretable\begin{tabular}{|*{\csv@columncount}{c|}}\csv@tablehead,
    table head=\hline\csvlinetotablerow\\\hline,
    late after line=\\,
    table foot=\\\hline,
    late after last line=\csv@tablefoot\end{tabular}\csv@posttable,
    command=\csvlinetotablerow},
}
\makeatother
\newcommand{\csvautotabularcenter}[2][]{\csvloop{autotabularcenter={#2},#1}}

% csv file from another question
\begin{filecontents*}{\jobname.csv}
name,givenname,matriculation,gender,grade
Maier,Hans,12345,m,1.0
Huber,Anna,23456,f,2.3
Weisbaeck,Werner,34567,m,5.0
\end{filecontents*}

\begin{document}
\csvautotabularcenter{\jobname.csv}
\end{document}

A version with \csvautobooktabularcenter:

\documentclass[11pt,a4paper,oldfontcommands]{memoir}

\usepackage{csvsimple} % For csv importing.

\makeatletter
\csvset{
  autotabularcenter/.style={
    file=#1,
    after head=\csv@pretable\begin{tabular}{|*{\csv@columncount}{c|}}\csv@tablehead,
    table head=\hline\csvlinetotablerow\\\hline,
    late after line=\\,
    table foot=\\\hline,
    late after last line=\csv@tablefoot\end{tabular}\csv@posttable,
    command=\csvlinetotablerow},
  autobooktabularcenter/.style={
    file=#1,
    after head=\csv@pretable\begin{tabular}{*{\csv@columncount}{c}}\csv@tablehead,
    table head=\toprule\csvlinetotablerow\\\midrule,
    late after line=\\,
    table foot=\\\bottomrule,
    late after last line=\csv@tablefoot\end{tabular}\csv@posttable,
    command=\csvlinetotablerow},
}
\makeatother
\newcommand{\csvautotabularcenter}[2][]{\csvloop{autotabularcenter={#2},#1}}
\newcommand{\csvautobooktabularcenter}[2][]{\csvloop{autobooktabularcenter={#2},#1}}

% csv file from another question
\begin{filecontents*}{\jobname.csv}
name,givenname,matriculation,gender,grade
Maier,Hans,12345,m,1.0
Huber,Anna,23456,f,2.3
Weisbaeck,Werner,34567,m,5.0
\end{filecontents*}

\begin{document}

\csvautotabularcenter{\jobname.csv}

\bigskip

\csvautobooktabularcenter{\jobname.csv}

\end{document}

I found the manual almost incomprehensible for the most part. But it mentions several times that you typically wouldn't use \csvautotabular or \csvautobooktabular in practice.

They suggest using \csvreader. Here is a minimal use case of \csvreader, which may be preferable for other people (as it was for me).

\csvreader[
  tabular=|c|c|r|c|r|,
  table head=\hline \bfseries{Name} & \bfseries{Given Name} & \bfseries{Matriculation} & \bfseries{Gender} & \bfseries{Grade} \\\hline,
  late after last line=\\\hline % horizontal line at the end of the table
]{
  grade.csv
}{}{\csvlinetotablerow}

Pros vs egreg's solution:

• More control over table header and column alignments
• Less overall code for a single table

Cons vs egreg's solution:

• More overall code if you're going to use it for many tables
