使用ICustomFunction返回一系列值

使用ICustomFunction返回一系列值

以下代码实现ICustomFunction并通过其方法返回一系列值。请查看生成的代码的Excel文件pdf以供参考。

创建一个带有函数CalculateCustomFunction的类。该类实现ICustomFunction

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
import java.util.ArrayList;
import com.aspose.cells.AbstractCalculationEngine;
import com.aspose.cells.CalculationData;
import com.aspose.cells.DateTime;
public class CustomFunctionStaticValue extends AbstractCalculationEngine {
@Override
public void calculate(CalculationData calculationData) {
calculationData.setCalculatedValue(new Object[][] { new Object[] { new DateTime(2015, 6, 12, 10, 6, 30), 2 },
new Object[] { 3.0, "Test" } });
}
}

现在在您的程序中使用上述函数。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(ReturningRangeOfValues.class);
Workbook wb = new Workbook();
Cells cells = wb.getWorksheets().get(0).getCells();
Cell cell = cells.get(0, 0);
cell.setArrayFormula("=MYFUNC()", 2, 2);
Style style = cell.getStyle();
style.setNumber(14);
cell.setStyle(style);
CalculationOptions copt = new CalculationOptions();
copt.setCustomFunction(new CustomFunctionStaticValue());
wb.calculateFormula(copt);
// Save to xlsx by setting the calc mode to manual
wb.getSettings().getFormulaSettings().setCalculationMode(CalcModeType.MANUAL);
wb.save(dataDir + "output.xlsx");
// Save to pdf
wb.save(dataDir + "output.pdf");
