Aspose.Cells提供AbstractCalculationEngine类,用于实现Microsoft Excel不支持的用户定义或自定义函数。
本文将解释如何从AbstractCalculationEngine返回值范围。
以下代码演示了使用AbstractCalculationEngine的用法,并通过其方法返回值范围。
创建一个带有函数CalculateCustomFunction的类。此类扩展AbstractCalculationEngine。

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。
