Descrizione

Questa macro ordina alfabeticamente una tabella di LibreOffice Writer in base alla colonna in cui è posizionato il cursore.

Il programma contiene quattro funzioni per:

  • Ordinare alfabeticamente la colonna in modo ascendente;
  • Ordina alfabeticamente la colonna in modo ascendente, escludendo la riga d'intestazione;
  • Ordinare alfabeticamente la colonna in modo discendente;
  • Ordinare alfabeticamente la colonna in modo discendente, escludendo la riga d'intestazione.

L'equivalente di questa macro è disponibile anche in forma di estensione, fate clic su questo collegamento per scaricare il file sortwritertable-1.0.0.oxt. Dopo averla scaricata ed installata, l'estensione aggiunge una nuova barra degli strumenti con 4 pulsanti, collegati alle quattro macro.
