Rückgabe eines Wertebereichs mit AbstractCalculationEngine, verwendet in Node.js über C++

Contents
[ ]

Der folgende Code zeigt die Verwendung der Klasse AbstractCalculationEngine und gibt den Wertebereich über ihre Methode zurück.

Erstellen Sie eine Klasse mit einer Funktion calculateCustomFunction. Diese Klasse implementiert AbstractCalculationEngine.

const AsposeCells = require("aspose.cells.node");

class CustomFunctionStaticValue extends AsposeCells.AbstractCalculationEngine {
calculate(data) {
data.setCalculatedValue([
[new Date(2015, 5, 12, 10, 6, 30), 2],
[3.0, "Test"]
]);
}
}

Verwenden Sie die oben erwähnte Funktion jetzt in Ihrem Programm

const AsposeCells = require("aspose.cells.node");

class CustomFunctionStaticValue extends AsposeCells.AbstractCalculationEngine {
calculate(data) {
data.setCalculatedValue([
[new Date(2015, 5, 12, 10, 6, 30), 2],
[3.0, "Test"]
]);
}
}

try {
const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Create workbook
const workbook = new AsposeCells.Workbook();
const cells = workbook.getWorksheets().get(0).getCells();

// Set formula
const cell = cells.get(0, 0);
cell.setArrayFormula("=MYFUNC()", 2, 2);

const style = cell.getStyle();
style.setNumber(14);
cell.setStyle(style);

// Set calculation options for formula
const calculationOptions = new AsposeCells.CalculationOptions();
calculationOptions.setCustomEngine(new CustomFunctionStaticValue());
workbook.calculateFormula(calculationOptions);

// Save to xlsx by setting the calc mode to manual
workbook.getSettings().getFormulaSettings().setCalculationMode(AsposeCells.CalcModeType.Manual);
workbook.save(dataDir + "output_out.xlsx");

// Save to pdf
workbook.save(dataDir + "output_out.pdf");
} catch (error) {
console.error(`Test failed: ${error.message}`);
throw error;
}
