Aspose.Cells - 排序数据
要使用 Aspose.Cells 对电子表格中的数据进行排序，只需在设置一些易于设置的单元格区域属性后调用 DataSorter.sorter() 方法。 Java代码如下：
Java
//Instantiating a Workbook object
Workbook workbook = new Workbook(dataDir + "AsposeDataInput.xls");
//Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.getWorksheets().get(0);
//Get the cells collection in the sheet
Cells cells = worksheet.getCells();
//Obtain the DataSorter object in the workbook
DataSorter sorter = workbook.getDataSorter();
//Set the first order
sorter.setOrder1(SortOrder.ASCENDING);
//Define the first key.
sorter.setKey1(0);
//Set the second order
sorter.setOrder2(SortOrder.ASCENDING);
//Define the second key
sorter.setKey2(1);
//Create a cells area (range).
CellArea ca = new CellArea();
//Specify the start row index.
ca.StartRow = 1;
//Specify the start column index.
ca.StartColumn = 0;
//Specify the last row index.
ca.EndRow = 9;
//Specify the last column index.
ca.EndColumn = 2;
//Sort data in the specified data range (A2:C10)
sorter.sort(cells, ca);
//Saving the excel file
workbook.save(dataDir + "AsposeSortedData_Out.xls");
