Tabellenzellen aus CSV-Datei automatisch formatieren

Question

Ich habe versucht, Beispiele aus5.4 Tabellen mit Zahlenformatierungaus csvsimpledem Paket, aber ohne Erfolg.

Jede Zeile in meinemcsv Datei hat 20 Felder,alle von ihnenhat ein Format wie x.xxxxxx. Hier ist die erste Zeile:

0.500000,0.614231,0.567667,0.580000,0.787222,0.510333,0.797333,0.732000,0.851228,0.804333,0.764000,0.730667,0.879667,0.778667,0.858333,0.726333,0.884000,0.772667,0.959545,0.919667

Ich möchte eine Tabelle erstellen, um die Daten auszudrucken, abergekürzt, ich meine, drucken Sie nur 3 Dezimalstellen, wie x.xxx.

Ich weiß, dass es \csvloop{}den Schlüssel tabular={}zum Angeben des Formats gibt (wie tabular={lSS[table-format=2.2e1]}aus dem oben zitierten Beispiel).

1. Da meine Tabelle 20 Spalten haben soll, ist es möglich,alles automatisch formatieren?

2. Welches Format soll es sein S[table-format=1.3]??

MWE

Der folgende Code erzeugt den FehlerYou can't use a prefix with \hskip.}
