  3. 3. LibreOffice a Linux Summer 2014 Elementi di un foglio L’unità fondamentale di immagazzinamento è la cartella di lavoro, in cui sono contenuti più fogli di lavoro. Ogni foglio è formato da una griglia di rettangoli (celle), delimitato da colonne e righe.
  4. 4. LibreOffice a Linux Summer 2014 Elementi di un foglio Una colonna è un gruppo di celle che si succedono verticalmente. Identificata con la lettera A, B, C, ecc. Una riga è un gruppo di celle che si susseguono orizzontalmente. Identificata dal numero 1,2,3, ecc.
