有没有办法使用 Apache POI 在 Excel 中创建数据透视表?

问题描述：

我目前正在研究 Excel 的自动化，并补充说我已经很好地利用了 Apache POI 库.

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

由于我的 excel 工作簿的各个列中存储了大量数据，因此我正在尝试创建数据透视表.

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

有没有办法使用 POI 创建数据透视表?

我的要求是我需要在新的 excel 工作簿或存储数据的同一工作簿中创建数据透视表.

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.

快速指南"已经过时了.

The 'Quick Guide' is quite out of date.

变更日志指的是这个bugzilla 问题已解决.

可以看到代码此处:

这是一个片段:

 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();
    }
