Is there any way to create a Pivot Table in Excel using Apache POI?

问题

I am currently working on the automation of Excel, and add such I have made a good use of the Apache POI library.

As I have so much data stored in my excel workbook in various columns, that I'm trying to create a pivot table.

Is there any way to create Pivot tables using POI ?

My requirement is that I need to create the pivot table in a new excel workbook or in the same workbook where I store my data.

The 'Quick Guide' is quite out of date.

The change log refers to this bugzilla issue as resolved.

You can see the code here:

Here is a snippet:

 public static void main(String[] args) throws FileNotFoundException, IOException, InvalidFormatException {
        XSSFWorkbook wb = new XSSFWorkbook();
        XSSFSheet sheet = (XSSFSheet) wb.createSheet();

        //Create some data to build the pivot table on
        setCellData(sheet);

        XSSFPivotTable pivotTable = sheet.createPivotTable(new AreaReference("A1:D4"), new CellReference("H5"));
        //Configure the pivot table
        //Use first column as row label
        pivotTable.addRowLabel(0);
        //Sum up the second column
        pivotTable.addColumnLabel(DataConsolidateFunction.SUM, 1);
        //Set the third column as filter
        pivotTable.addColumnLabel(DataConsolidateFunction.AVERAGE, 2);
        //Add filter on forth column
        pivotTable.addReportFilter(3);

        FileOutputStream fileOut = new FileOutputStream("ooxml-pivottable.xlsx");
        wb.write(fileOut);
        fileOut.close();
    }

No you cant.refer here

• Charts You can not currently create charts. You can however create a chart in Excel, modify the chart data values using HSSF and write a new spreadsheet out. This is possible because POI attempts to keep existing records intact as far as possible.

• Macros Macros can not be created. However, reading and re-writing files containing macros will safely preserve the macros.

• Pivot Tables Generating pivot tables is not supported. It has been reported that files containing pivot tables can be read and re-written safely.
