Adapter toutes les colonnes de la feuille de calcul sur une seule page PDF avec JavaScript via C++

Adapter les colonnes de la feuille de calcul sur une seule page PDF

PdfSaveOptions.allColumnsInOnePagePerSheet assure que toutes les colonnes d’une feuille sont rendues sur une seule page PDF, même si les lignes peuvent s’étendre sur plusieurs pages en fonction des données de la feuille.

Le code d’exemple ci-dessous montre comment utiliser la propriété PdfSaveOptions.allColumnsInOnePagePerSheet pour afficher une grande feuille de calcul de 100 colonnes.

<!DOCTYPE html>
<html>
    <head>
        <title>Save Workbook to PDF Example</title>

    <body>
        <h1>Save Workbook to PDF Example</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx" />
        <button id="runExample">Run Example</button>
        <a id="downloadLink" style="display: none;">Download Result</a>
