使用Java创建数据透视表并导出为PDF的方法

// 1.创建一个workbook
 Workbook workbook = new Workbook();
 // 2.设置样例数据
 Object sourceData = new Object[][]{
     {"Order ID", "Product", "Category", "Amount", "Date", "Country"},
     {1, "Bose 785593-0050", "Consumer Electronics", 4270, new GregorianCalendar(2018, 0, 6), "United States"},
     {2, "Canon EOS 1500D", "Consumer Electronics", 8239, new GregorianCalendar(2018, 0, 7), "United Kingdom"},
     {3, "Haier 394L 4Star", "Consumer Electronics", 617, new GregorianCalendar(2018, 0, 8), "United States"},
     {4, "IFB 6.5 Kg FullyAuto", "Consumer Electronics", 8384, new GregorianCalendar(2018, 0, 10), "Canada"},
     {5, "Mi LED 40inch", "Consumer Electronics", 2626, new GregorianCalendar(2018, 0, 10), "Germany"},
     {6, "Sennheiser HD 4.40-BT", "Consumer Electronics", 3610, new GregorianCalendar(2018, 0, 11), "United States"},
     {7, "Iphone XR", "Mobile", 9062, new GregorianCalendar(2018, 0, 11), "Australia"},
     {8, "OnePlus 7Pro", "Mobile", 6906, new GregorianCalendar(2018, 0, 16), "New Zealand"},
     {9, "Redmi 7", "Mobile", 2417, new GregorianCalendar(2018, 0, 16), "France"},
     {10, "Samsung S9", "Mobile", 7431, new GregorianCalendar(2018, 0, 16), "Canada"},
     {11, "OnePlus 7Pro", "Mobile", 8250, new GregorianCalendar(2018, 0, 16), "Germany"},
     {12, "Redmi 7", "Mobile", 7012, new GregorianCalendar(2018, 0, 18), "United States"},
     {13, "Bose 785593-0050", "Consumer Electronics", 1903, new GregorianCalendar(2018, 0, 20), "Germany"},
     {14, "Canon EOS 1500D", "Consumer Electronics", 2824, new GregorianCalendar(2018, 0, 22), "Canada"},
     {15, "Haier 394L 4Star", "Consumer Electronics", 6946, new GregorianCalendar(2018, 0, 24), "France"},
 };
 //创建worksheet
 IWorksheet worksheet = workbook.getWorksheets().get(0);
 worksheet.getRange("G1:L16").setValue(sourceData);
 worksheet.getRange("G:L").setColumnWidth(15);
 //3.设置PivotTable
 IPivotCache pivotcache = workbook.getPivotCaches().create(worksheet.getRange("G1:L16"));
 IPivotTable pivottable = worksheet.getPivotTables().add(pivotcache, worksheet.getRange("A1"), "pivottable1");
 worksheet.getRange("J1:J16").setNumberFormat("$#,##0.00");
 //4.配置透视表的字段
 IPivotField field_Category = pivottable.getPivotFields().get("Category");
 field_Category.setOrientation(PivotFieldOrientation.ColumnField);
 IPivotField field_Product = pivottable.getPivotFields().get("Product");
 field_Product.setOrientation(PivotFieldOrientation.RowField);
 IPivotField field_Amount = pivottable.getPivotFields().get("Amount");
 field_Amount.setOrientation(PivotFieldOrientation.DataField);
 field_Amount.setNumberFormat("$#,##0.00");
 IPivotField field_Country = pivottable.getPivotFields().get("Country");
 field_Country.setOrientation(PivotFieldOrientation.PageField);
 worksheet.getRange("A:D").getEntireColumn().autoFit();
 // 5.导出PDF
 workbook.save("CreatePivotTable.pdf", SaveFileFormat.Pdf);
