How to change the pivot table style from default blue to other colors using apache-poi

问题

When i create a pivot table using the below code, it comes with some default template style(blue). How to change this default style of pivot table using apache-poi library

pivotTable = sheet2.createPivotTable(aref, new CellReference("A4"), sheet1);

What I want.

What i am able to generate through code

XXSPivotTable is using named style PivotStyleLight16 per default. See setDefaultPivotTableDefinition.

There is no method for changing this in high level XSSF classes until now. Bu we can get the underlying low level CTPivotTableStyle form the CTPivotTableDefinition got via XSSFPivotTable.getCTPivotTableDefinition. Then we can use CTPivotTableStyle.setName to set another named style:

pivotTable.getCTPivotTableDefinition().getPivotTableStyleInfo().setName("PivotStyleMedium7");

Complete example:

import java.io.FileOutputStream;

import org.apache.poi.ss.*;
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.ss.util.*;
import org.apache.poi.xssf.usermodel.*;

class CreatePivotTableStyle {

 public static void main(String[] args) throws Exception {

  try (Workbook workbook = new XSSFWorkbook(); 
       FileOutputStream fileout = new FileOutputStream("Excel.xlsx") ) {

   Sheet pivotSheet = workbook.createSheet("Pivot");
   Sheet dataSheet = workbook.createSheet("Data");

   Row row;
   Cell cell;
   Object[][] data = new Object[][]{
    new Object[]{"Name", "Count"},
    new Object[]{"A", 2d},
    new Object[]{"B", 4d},
    new Object[]{"A", 1d},
    new Object[]{"B", 7d}
   };
   for (int r = 0; r < data.length; r++) {
    row = dataSheet.createRow(r);
    Object[] rowData = data[r];
    for (int c = 0; c < rowData.length; c++) {
     cell = row.createCell(c);
     if (rowData[c] instanceof String) {
      cell.setCellValue((String)rowData[c]);
     } else if (rowData[c] instanceof Double) {
      cell.setCellValue((Double)rowData[c]);
     }
    }
   }

   AreaReference arerReference = new AreaReference("A1:B5", SpreadsheetVersion.EXCEL2007);

   XSSFPivotTable pivotTable = ((XSSFSheet)pivotSheet).createPivotTable(arerReference, new CellReference("A4"), dataSheet);

   pivotTable.addRowLabel(0);
   pivotTable.addColumnLabel(DataConsolidateFunction.SUM, 1, "Sum of count");

   pivotTable.getCTPivotTableDefinition().getPivotTableStyleInfo().setName("PivotStyleMedium7");

   workbook.write(fileout);

  }

 }
}

Names of possible named styles can be got from Excels GUI in PivotTable Tools tab - Design.
