  3. Klicka på Ändra.
  4. Välj de stilalternativ du vill använda med flikarna i dialogrutan Formatcells.

Använder Aspose.Cells for JavaScript via C++

Följande exempel visar hur man använder Style.update()-metoden.

Skapa och modifiera en stil

Detta exempel skapar ett Style-objekt, tillämpar det på ett cellområde och ändrar Style-objektet. Ändringarna tillämpas automatiskt på cellen och det område varpå stilen användes.

Modifiera en befintlig stil

Detta exempel använder en enkel mall Excel-fil där en stil som heter Procent redan har tillämpats på en omfattning. Exemplet:

  1. hämtar stilen,
  2. skapar en stilobjekt och
  3. modifierar stilformatering.

Modifieringarna tillämpas automatiskt på området där stilen applicerades.
