Définition de la formule pour une plage nommée
Comme dans l’application Excel, les API Aspose.Cells offrent la possibilité de spécifier une formule pour une plage nommée en utilisant sa propriété Range.refersTo. Il peut y avoir de nombreux scénarios d’utilisation pour cette fonctionnalité, dont quelques-uns sont détaillés ci-dessous.
Définir une formule simple pour une plage nommée
Une formule simple pourrait être une référence à une autre cellule dans la même feuille de calcul (ou dans une feuille de calcul différente). L’exemple suivant crée une plage nommée dans une nouvelle feuille et défini sa référence à une autre cellule.

<h1>Create Named Range Example</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<button id="runExample">Run Example</button>

const { Workbook, SaveFormat, Worksheet, Cell } = AsposeCells;
AsposeCells.onReady({

fontPath: "/fonts/",
fontList: [
"arial.ttf",
"NotoSansSC-Regular.ttf"
]
}).then(() => {
console.log("Aspose.Cells initialized");
});
document.getElementById('runExample').addEventListener('click', async () => {
// Create an instance of Workbook
const book = new Workbook();
// Get the WorksheetCollection
const worksheets = book.worksheets;
// Add a new Named Range with name "NewNamedRange"
const index = worksheets.names.add("NewNamedRange");
// Access the newly created Named Range
const name = worksheets.names.get(index);
// Set RefersTo property of the Named Range to a formula. Formula references another cell in the same worksheet
name.refersTo = "=Sheet1!$A$3";
// Set the formula in the cell A1 to the newly created Named Range
worksheets.get(0).cells.get("A1").formula = "NewNamedRange";
// Insert the value in cell A3 which is being referenced in the Named Range
worksheets.get(0).cells.get("A3").value = "This is the value of A3";
// Calculate formulas
book.calculateFormula();
// Save the result in XLSX format
const outputData = book.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'output_out.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Workbook created and saved. Click the download link to get the file.</p>';
});

Définir une formule complexe pour une plage nommée
Une formule complexe pourrait être n’importe quoi, comme une plage dynamique ou une formule s’étalant sur plusieurs cellules dans différentes feuilles de calcul. L’exemple suivant crée une plage dynamique en utilisant la fonction INDEX pour obtenir la valeur d’une liste en fonction de son emplacement.
