如何清理使用apache poi生成的excel文件中的单元格之间的差距

我使用apache poi来生成一个excel文件文件，我从数据库导入数据，我使用了两个查询，但是当我填充单元格，但我有两个查询的结果之间的差距，如下面的图片

和正常情况下应该是这样的（图2）

这里是我使用的代码

public static void Excel () { XSSFWorkbook workbook = new XSSFWorkbook(); XSSFSheet sheet1 = workbook.createSheet("Etat"); //***************HEADER Cell cell1 = sheet1.createRow(2).createCell(1); cell1.setCellValue("NUMEROS"); sheet1.addMergedRegion(new CellRangeAddress(2,2,1,4)); // new Region(2,(short)1,2,(short)4)); XSSFCellStyle CellST = workbook.createCellStyle(); XSSFCellStyle CellST2 = workbook.createCellStyle(); XSSFFont fonte = workbook.createFont(); fonte.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD); fonte.setFontHeightInPoints((short) 7); fonte.setFontName("Courier New"); CellST.setAlignment(HSSFCellStyle.ALIGN_CENTER); CellST.setFont(fonte); CellST.setFillForegroundColor(IndexedColors.YELLOW.getIndex()); CellST.setFillPattern(CellStyle.SOLID_FOREGROUND); CellST.setBottomBorderColor(Red); cell1.setCellStyle(CellST); Cell cell2 = sheet1.createRow(3).createCell(1); cell2.setCellValue("D'Or-"); cell2.setCellStyle(CellST); Cell cell3 = sheet1.createRow(4).createCell(1); cell3.setCellValue("dre"); cell3.setCellStyle(CellST); Cell cell4 = sheet1.getRow(3).createCell(2); cell4.setCellValue("des"); cell4.setCellStyle(CellST); Cell cell5 = sheet1.getRow(4).createCell(2); cell5.setCellValue("requisitions"); cell5.setCellStyle(CellST); ... ... ... //*****************QUERIES & REPORT GENERATION try { String sql1 = "select ordre.num_ordre , parcelle.code_parcelle, parcelle.num_req , prop_dite.lbl_fr, " + "prop_dite.lbl_ar , parcelle.surface_adop , mappe.mappe," + "(select array_to_string(array_agg(consistance.lib_consistance), '+'::text)" + "from consistance where id_consistance in (select id_consistance from " + "consist_parcelle where id_parcelle = parcelle.id_parcelle)) AS consistance " + "from ordre , parcelle , prop_dite , mappe ,mappe_parcelle where " + "ordre.id_parcelle = parcelle.id_parcelle and prop_dite.id_prop = " + "parcelle.id_prop and mappe_parcelle.id_parcelle= parcelle.id_parcelle and " + "mappe_parcelle.id_mappe= mappe.id_mappe and mappe_parcelle.priorite=0"; String sql2 = "select ordre.ordre_ser,( ordre.id_personne, ordre.cts, ordre.htiers ) ," + "CASE when ordre.htiers = 1 then 'Heritiers de '::text else ''::text END || " + "(personne.nom_pers::text || ' '::text) || personne.prenom_pers::text" + "|| case when ordre.cts = 1 then ' et CTS'::text else ''::text END " + "AS lbl, adresse.lib_adresse , adresse.lib_adresse_ar from personne " + ", ordre , adresse where adresse.id_adresse = personne.id_adresse " + "and personne.id_personne = ordre.id_personne order by ordre.ordre_ser ; "; Connection conn = conectar(); Statement st = conn.createStatement(); ResultSet rs1 = st.executeQuery(sql1); int i =5; while (rs1.next()) { Cell cell25 = sheet1.createRow(i).createCell(1); cell25.setCellValue(rs1.getString("num_ordre")); cell25.setCellStyle(CellST); Cell cell26 = sheet1.getRow(i).createCell(4); cell26.setCellValue(rs1.getString("code_parcelle")); cell26.setCellStyle(CellST); Cell cell27 = sheet1.getRow(i).createCell(4); cell27.setCellValue(rs1.getString("code_parcelle")); cell27.setCellStyle(CellST); int rowcount = rs1.getRow(); Cell cell31 = sheet1.getRow(i).createCell(9); cell31.setCellValue(rs1.getString("lbl_fr")); cell31.setCellStyle(CellST); Cell cell32 = sheet1.getRow(i).createCell(10); cell32.setCellValue(rs1.getString("lbl_ar")); cell32.setCellStyle(CellST); Cell cell33 = sheet1.getRow(i).createCell(11); cell33.setCellValue(rs1.getString("surface_adop")); cell33.setCellStyle(CellST); Cell cell34 = sheet1.getRow(i).createCell(12); cell34.setCellValue(rs1.getString("mappe")); cell34.setCellStyle(CellST); Cell cell35 = sheet1.getRow(i).createCell(13); cell35.setCellValue(rs1.getString("consistance")); cell35.setCellStyle(CellST); i++; } rs1.close(); st.close(); Statement st2 = conn.createStatement(); ResultSet rs2 = st2.executeQuery(sql2); int j =5; while (rs2.next()) { Cell cell28 = sheet1.createRow(5).createCell(5); cell28.setCellValue(rs2.getString("lbl")); cell28.setCellStyle(CellST); Cell cell29 = sheet1.getRow(j).createCell(7); cell29.setCellValue(rs2.getString("lib_adresse")); cell29.setCellStyle(CellST); Cell cell30 = sheet1.getRow(j).createCell(8); cell30.setCellValue(rs2.getString("lib_adresse_ar")); cell30.setCellStyle(CellST); int rowcount2 = rs2.getRow(); j++; } rs2.close(); st2.close(); DateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy"); Calendar cal = Calendar.getInstance(); String date = dateFormat.format(cal.getTime()); FileOutputStream fileOut = new FileOutputStream("C:\\Saadia\\Etatxxx"+date+".xlsx"); workbook.write(fileOut); fileOut.close(); System.out.println("Your excel file has been generated!"); } catch (Exception e ) { e.printStackTrace(); } } 

我认为问题来自单元格的数量和while循环，我做了许多改变，但他们没有工作，希望能帮助解决这个问题。

任何帮助将不胜感激

Answer 1

我认为这个问题是与行：

 Cell cell28 = sheet1.createRow(5).createCell(5); 

您正在第二个循环中创build新行，并向下移动之前创build的行。 使用getRow()来代替。 也许你应该使用索引j而不是硬编码5 ：

 Cell cell28 = sheet1.getRow(j).createCell(5);
