Auto adatta le righe per celle unite con Node.js tramite C++
Come utilizzare AutoFitMergedCellsType per l’adattamento automatico delle righe
Aspose.Cells for Node.js via C++ supporta questa funzionalità tramite l’API AutoFitterOptions.autoFitMergedCellsType. Usando questa API, è possibile adattare automaticamente le righe in un foglio di lavoro, inclusi le celle unite. Ecco un elenco di tutti i possibili tipi di auto-adattamento delle celle unite:
- Nessuna
- Prima riga
- Ultima riga
- Ogni riga
Autoadattamento righe per celle unite
Vedi il seguente codice, crea un oggetto workbook e aggiunge più fogli di lavoro. Utilizza metodi diversi per le operazioni di autofit in ogni foglio di lavoro. Lo screenshot mostra i risultati dopo l’esecuzione del codice di esempio.

Codice di esempio Node.js
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "sample.xlsx");
// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();
// Obtaining the reference of the newly added worksheet
const sheet1 = workbook.getWorksheets().get(0);
// Create a range A1:B2
const range = sheet1.getCells().createRange(0, 0, 2, 2);
// Merge the cells
range.merge();
// Insert value to the merged cell A1
sheet1.getCells().get(0, 0).setValue("A quick brown fox jumps over the lazy dog. A quick brown fox jumps over the lazy dog....end");
// Create a style object
const style = sheet1.getCells().get(0, 0).getStyle();
// Set wrapping text on
style.setIsTextWrapped(true);
// Apply the style to the cell
sheet1.getCells().get(0, 0).setStyle(style);
// Create an object for AutoFitterOptions
const options = new AsposeCells.AutoFitterOptions();
// Only expands the height of the first row.
options.setAutoFitMergedCellsType(AsposeCells.AutoFitMergedCellsType.FirstLine);
// Autofit rows in the sheet (including the merged cells)
sheet1.autoFitRows(options);
let index = workbook.getWorksheets().add();
const sheet2 = workbook.getWorksheets().get(index);
sheet2.setName("Sheet2");
// Create a range A1:B2
const range2 = sheet2.getCells().createRange(0, 0, 2, 2);
// Merge the cells
range2.merge();
// Insert value to the merged cell A1
sheet2.getCells().get(0, 0).setValue("A quick brown fox jumps over the lazy dog. A quick brown fox jumps over the lazy dog....end");
// Create a style object
const style2 = sheet2.getCells().get(0, 0).getStyle();
// Set wrapping text on
style2.setIsTextWrapped(true);
// Apply the style to the cell
sheet2.getCells().get(0, 0).setStyle(style2);
// Create an object for AutoFitterOptions
const options2 = new AsposeCells.AutoFitterOptions();
// Only expands the height of the last row.
options2.setAutoFitMergedCellsType(AsposeCells.AutoFitMergedCellsType.LastLine);
// Autofit rows in the sheet (including the merged cells)
sheet2.autoFitRows(options2);
index = workbook.getWorksheets().add();
const sheet3 = workbook.getWorksheets().get(index);
sheet3.setName("Sheet3");
// Create a range A1:B2
const range3 = sheet3.getCells().createRange(0, 0, 2, 2);
// Merge the cells
range3.merge();
// Insert value to the merged cell A1
sheet3.getCells().get(0, 0).setValue("A quick brown fox jumps over the lazy dog. A quick brown fox jumps over the lazy dog....end");
// Create a style object
const style3 = sheet3.getCells().get(0, 0).getStyle();
// Set wrapping text on
style3.setIsTextWrapped(true);
// Apply the style to the cell
sheet3.getCells().get(0, 0).setStyle(style3);
// Create an object for AutoFitterOptions
const options3 = new AsposeCells.AutoFitterOptions();
// Only expands the height of each row.
options3.setAutoFitMergedCellsType(AsposeCells.AutoFitMergedCellsType.EachLine);
// Autofit rows in the sheet (including the merged cells)
sheet3.autoFitRows(options3);
index = workbook.getWorksheets().add();
const sheet4 = workbook.getWorksheets().get(index);
sheet4.setName("Sheet4");
// Create a range A1:B2
const range4 = sheet4.getCells().createRange(0, 0, 2, 2);
// Merge the cells
range4.merge();
// Insert value to the merged cell A1
sheet4.getCells().get(0, 0).setValue("A quick brown fox jumps over the lazy dog. A quick brown fox jumps over the lazy dog....end");
// Create a style object
const style4 = sheet4.getCells().get(0, 0).getStyle();
// Set wrapping text on
style4.setIsTextWrapped(true);
// Apply the style to the cell
sheet4.getCells().get(0, 0).setStyle(style4);
// Create an object for AutoFitterOptions
const options4 = new AsposeCells.AutoFitterOptions();
// Ignore merged cells.
options4.setAutoFitMergedCellsType(AsposeCells.AutoFitMergedCellsType.None);
// Autofit rows in the sheet (not including the merged cells)
sheet4.autoFitRows(options4);
// Save the Excel file
workbook.save("out.xlsx");
