指定在刷新数据透视表时数据透视表是否兼容Excel2003

Aspose.Cells提供PivotTable.IsExcel2003Compatible属性，您可以使用该属性来指定在刷新数据透视表时该数据透视表是否与Excel 2003兼容。如果设置为true，则字符串长度必须小于或等于255个字符，因此，如果字符串长度大于255个字符，将被截断。如果设置为false，字符串将不受上述限制。默认值为true。

指定在刷新数据透视表时数据透视表是否兼容Excel2003

以下示例代码说明了如何使用PivotTable.IsExcel2003Compatible属性。原始字符串长度为383个字符。但是当将PivotTable.IsExcel2003Compatible属性设置为true并刷新数据透视表时，数据透视表的B5单元格的数据被截断为255个字符。然而，当PivotTable.IsExcel2003Compatible属性设置为false并再次刷新数据透视表时，数据透视表的B5单元格的数据不会被截断，仍保持383个字符。请下载此代码中使用的示例Excel文件、生成的输出Excel文件以及控制台输出以供参考。还请阅读代码内的注释以更好地理解此属性。

// The path to the resource directory.
String dataDir = Utils.getSharedDataDir(IsPivotTableCompatibleForExcel2003.class) + "Conversion/";
		
//Load source excel file containing sample pivot table
Workbook wb = new Workbook(dataDir + "sample-pivot-table.xlsx");

//Access first worksheet that contains pivot table data
Worksheet dataSheet = wb.getWorksheets().get(0);

//Access cell A3 and sets its data
Cells cells = dataSheet.getCells();
Cell cell = cells.get("A3");
cell.putValue("FooBar");

//Access cell B3 and sets its data
//We set B3 a very long string which has more than 255 characters
String longStr = "Very long text 1. very long text 2. very long text 3. very long text 4. very long text 5. very long text 6. very long text 7. very long text 8. very long text 9. very long text 10. very long text 11. very long text 12. very long text 13. very long text 14. very long text 15. very long text 16. very long text 17. very long text 18. very long text 19. very long text 20. End of text.";
cell = cells.get("B3");
cell.putValue(longStr);

//Print the length of cell B3 string
System.out.println("Length of original data string: " + cell.getStringValue().length());

//Access cell C3 and sets its data
cell = cells.get("C3");
cell.putValue("closed");

//Access cell D3 and sets its data
cell = cells.get("D3");
cell.putValue("2016/07/21");

//Access the second worksheet that contains pivot table
Worksheet pivotSheet = wb.getWorksheets().get(1);

//Access the pivot table
PivotTable pivotTable = pivotSheet.getPivotTables().get(0);

//IsExcel2003Compatible property tells if PivotTable is compatible for Excel2003 while refreshing PivotTable.
//If it is true, a string must be less than or equal to 255 characters, so if the string is greater than 255 characters,
//it will be truncated. If false, a string will not have the aforementioned restriction.
//The default value is true.
pivotTable.setExcel2003Compatible(true);
pivotTable.refreshData();
pivotTable.calculateData();

//Check the value of cell B5 of pivot sheet.
//It will be 255 because we have set IsExcel2003Compatible property to true
//All the data after 255 characters has been truncated
Cell b5 = pivotSheet.getCells().get("B5");
System.out.println("Length of cell B5 after setting IsExcel2003Compatible property to True: " + b5.getStringValue().length());

//Now set IsExcel2003Compatible property to false and again refresh
pivotTable.setExcel2003Compatible(false);
pivotTable.refreshData();
pivotTable.calculateData();

//Now it will print 383 the original length of cell data
//The data has not been truncated now.
b5 = pivotSheet.getCells().get("B5");
System.out.println("Length of cell B5 after setting IsExcel2003Compatible property to False: " + b5.getStringValue().length());

//Set the row height and column width of cell B5 and also wrap its text
pivotSheet.getCells().setRowHeight(b5.getRow(), 100);
pivotSheet.getCells().setColumnWidth(b5.getColumn(), 65);
Style st = b5.getStyle();
st.setTextWrapped(true);
b5.setStyle(st);

//Save workbook in xlsx format
wb.save(dataDir + "output.xlsx", SaveFormat.XLSX);

控制台输出

以下是执行上述示例代码时使用给定的示例Excel文件的控制台输出。

 Length of original data string: 383

Length of cell B5 after setting IsExcel2003Compatible property to True: 255

Length of cell B5 after setting IsExcel2003Compatible property to False: 383
