I am trying to sort a table I created with the pgfplotstable package and I can't find out why it is not working.
\pgfplotstableset{col sep=semicolon, use comma, fixed, set thousands separator={}}
\pgfplotstableread
{
Matrikelnummer;Note
1010123;1.4
1010121;2.3
1010122;1.1
}\loadedtable
\pgfplotstabletypeset[sort, sort key={Matrikelnummer}]\loadedtable
When I change the sort key to "Note" it works like a charm. But the example above simply does not change the order.
