Wie man Daten von Tableview Iterate, um sie nach Microsoft Excel zu exportieren?

Question

Ich brauche Hilfe beim Iterieren von Daten aus der Tabellenansicht, um sie nach Excel zu exportieren. Jedes Mal, wenn ich auf eine Schaltfläche drücke, werden nur die Daten der ersten Zeile aus der Tabellenansicht auf meinem Excel-Blatt angezeigt.

Ich hoffe, Sie bekommen, was ich sage das ist mein Code

Especialy auf diesem Abschnitt des Codes ich weiß nicht, wie dies zu wiederholen, dass ich alle Elemente auf dem Tisch-Ansicht und den Export bekommen könnte es auf Excel Blatt in mehreren

      cell = row.createCell(2);

      cell.setCellValue(tblContract.getCellData(1).toString()); 

      cell = row.createCell(5); 
      cell.setCellValue(tblfirst.getCellData(1).toString()); 

      cell = row.createCell(6); 
      cell.setCellValue(tblFinal.getCellData(1).toString()); 

      cell = row.createCell(7); 
      cell.setCellValue(tblBank.getCellData(1).toString()); 

      cell = row.createCell(8); 
      cell.setCellValue(tblDisclosure.getCellData(1).toString()); 

      cell = row.createCell(9); 
      cell.setCellValue(tblNema.getCellData(1).toString()); 

      cell = row.createCell(10); 
      cell.setCellValue(tblBudgetRe .getCellData(1).toString()); 

      cell = row.createCell(11); 
      cell.setCellValue(tblBudgetPro.getCellData(1).toString()); 

      cell = row.createCell(12); 
      cell.setCellValue(tblBegin.getCellData(1).toString()); 

      cell = row.createCell(13); 
      cell.setCellValue(tblComments.getCellData(1).toString()); 

brauchen Hilfe?

Answer 1

Sie müssen für jede Zeile neue HSSFRow() Objekte erstellen. Im Moment erstellen Sie nur eine Zeile und übergeben nur die Daten der ersten Zeile. Deshalb sehen Sie in Ihrem Excel nur Ihre erste Zeile. Verwenden Sie loop, um HSSFRows für jeden Ihrer tableRow neu zu erstellen. Verwenden Sie die folgende

HSSFRow row =null; 

int i=1; 
for(Items item: tableViewForExcel.getItems()){ 
     row= spreadsheet.createRow(i); 
     row.createCell(1).setCellValue(item.getComponent); 
     //.... add other column data as well 
     i++; 
} 

oder verwenden Sie die folgende

HSSFRow row =null; 

     for(int i=0;i<tableViewForExcel.getItems().size();i++){ 
      row= spreadsheet.createRow(i);   
      for(int j=0; j< tableViewForExcel.getColumns().size();j++) {     
       if(tableViewForExcel.getColumns().get(j).getCellData(i) != null) { 
        row.createCell(j).setCellValue(tableViewForExcel.getColumns().get(j).getCellData(i).toString()); 
       }else{ 
        row.createCell(j).setCellValue(""); 
       } 
      } 
     }
