Using formula in pivot table

Hi,

Can you please provide an example of how to subtract two columns in pivot table using aspose java.

Thanks,

Asha

Hi,


I think you may use addCalculatedField method of PivotTable to implement your desired formula, see the sample code below/ I have written an example for your reference. This example just gives you an idea on how to accomplish the task, you may write your own code and formula accordingly for your needs based on your source data range.

Sample code:

//Instantiating an Workbook object
Workbook workbook = new Workbook();

//Obtaining the reference of the first worksheet
Worksheet sheet = workbook.getWorksheets().get(0);

//Name the sheet

sheet.setName(“Data”);

Cells cells = sheet.getCells();

//Setting the values to the cells

Cell cell = cells.get(“A1”);

cell.setValue(“Employee”);

cell = cells.get(“B1”);

cell.setValue(“Quarter”);

cell = cells.get(“C1”);

cell.setValue(“Product”);

cell = cells.get(“D1”);

cell.setValue(“Continent”);

cell = cells.get(“E1”);

cell.setValue(“Country”);

cell = cells.get(“F1”);

cell.setValue(“Sale”);


cell = cells.get(“A2”);

cell.setValue(“David”);

cell = cells.get(“A3”);

cell.setValue(“David”);

cell = cells.get(“A4”);

cell.setValue(“David”);

cell = cells.get(“A5”);

cell.setValue(“David”);

cell = cells.get(“A6”);

cell.setValue(“James”);

cell = cells.get(“A7”);

cell.setValue(“James”);

cell = cells.get(“A8”);

cell.setValue(“James”);

cell = cells.get(“A9”);

cell.setValue(“James”);

cell = cells.get(“A10”);

cell.setValue(“James”);

cell = cells.get(“A11”);

cell.setValue(“Miya”);

cell = cells.get(“A12”);

cell.setValue(“Miya”);

cell = cells.get(“A13”);
