如何使用Java按列單元格值對excel表進行排序？

Question

我遇到了excel表列的順序問題。我的計劃的樣品結果：

PAGE | NAME 
106 | 29100004-01 
108 | 36110001-01 
11 | 29100020-01 
110 | 24000017-01 
112 | 32430002-01 
114 | 3831000201A 
116 | 26150003-01 
118 | 52210001-01 
120 | 35100008-01 
122 | 29100009-01 
124 | 32400014-01 
126 | 32330005-01 
128 | 35100001-01 
13 | 26234201-03 
130 | 27514401-01 
133 | 27510002-01 

我用下面的源：

XSSFWorkbook workbook = new XSSFWorkbook(); 
// Create a blank sheet 
XSSFSheet sheet = workbook.createSheet("WORKPACK DATA"); 

// This data needs to be written (Object[]) 
Map<String, Object[]> data = new TreeMap<String, Object[]>(); 

String strPreviousPage =""; 

for (int i = 0; i < pdDoc.getNumberOfPages(); i++) 
{ 
    PDPage CurrentPage = (PDPage) allPages.get(i); 
    pdfStripper.extractRegions(CurrentPage); 
    int currentRow = i + 1; 
    Text = pdfStripper.getTextForRegion("KeyWordRegion"); 
    if (Text.toLowerCase().contains(keyword.toLowerCase())) 
    { 
     TextCRI = pdfStripper.getTextForRegion("ExternalIdent"); 
     String str = TextCRI.replace("\r\n", ""); 
     String str2 = str.replace(" ", ""); 

     if (str2.equalsIgnoreCase(strPreviousPage)) 
     {  
      System.out.println("Keyword found on current page!"); 
     } 
     else 
     { 
      System.out.println("Keyword found on current page!"); 
      data.put(Integer.toString(currentRow), new Object[] {i + 1, str2 }); 
     } 
     strPreviousPage = str2; 
    } 
    else 
    { 
     System.out.println("Keyword NOT found on current page!"); 
    }  
} 
pdDoc.close(); 

// Iterate over data and write to sheet 
Set<String> keyset = data.keySet(); 
int rownum = 0; 
for (String key : keyset) 
{ 
    Row row = sheet.createRow(rownum++); 
    Object[] objArr = data.get(key); 
    int cellnum = 0; 
    for (Object obj : objArr) 
    { 
     Cell cell = row.createCell(cellnum++); 
     if (obj instanceof String) 
      cell.setCellValue((String) obj); 
     else if (obj instanceof Integer) 
      cell.setCellValue((Integer) obj); 
    } 
} 

try 
{ 
    // Write the workbook in file system 
    FileOutputStream out = new FileOutputStream(new File("C:\\INPUT\\STANIMIROV.xlsx")); 
    workbook.write(out); 
    out.close(); 
    System.out.println("C:\\INPUT\\STANIMIROV.xlsx written successfully on disk."); 
} 
catch (Exception e) 
{ 
    e.printStackTrace(); 
} 

我怎樣才能在表中的數據進行排序？我需要PAGES命令爲11,13,15 ......非10,101,12,125,13,​​131 ......

您需要將列字符串轉換爲整數，例如Integer.parseInt(value)。你所看到的是基於ASCII值進行排序，而不是數值。
