Entfernen Sie alle Grenzen auf einem bestimmten Excel-Arbeitsblatt mit Apache POI

Question

Ich verwende Apache POI, um eine Excel-Datei zu generieren. Ich muss alle Ränder in meinem Arbeitsblatt löschen. Wie kann ich dies mit Apache PIO 3.11 und Microsoft Excel 2007 erreichen? Hier

ist der Code Ich habe bisher:

package models; 

import org.apache.poi.hssf.usermodel.HSSFWorkbook; 
import org.apache.poi.ss.usermodel.*; 
import org.apache.poi.ss.util.CellRangeAddress; 

import java.io.FileOutputStream; 
import java.util.List; 
public class Excel { 

    public static void writeDocument() { 
     Workbook workbook = new HSSFWorkbook(); 
     Sheet sheet = workbook.createSheet("sheet"); 
     //first font 
     Font font1 = workbook.createFont(); 
     font1.setBoldweight(Font.BOLDWEIGHT_BOLD); 
     //first style 
     CellStyle style1 = workbook.createCellStyle(); 
     style1.setBorderLeft(CellStyle.BORDER_NONE); 
     style1.setBorderRight(CellStyle.BORDER_NONE); 
     style1.setBorderBottom(CellStyle.BORDER_NONE); 
     style1.setBorderTop(CellStyle.BORDER_NONE); 

     //second style 
     CellStyle style2 = workbook.createCellStyle(); 
     style2.setFont(font1); 
     style2.setVerticalAlignment(CellStyle.VERTICAL_CENTER); 
     style2.setAlignment(CellStyle.ALIGN_CENTER); 
     style2.setFillForegroundColor(IndexedColors.ORANGE.getIndex()); 
     style2.setFillPattern(CellStyle.SOLID_FOREGROUND); 
     style2.setBorderBottom(CellStyle.BORDER_THIN); 
     style2.setBottomBorderColor(IndexedColors.GREY_25_PERCENT.getIndex()); 
     style2.setBorderLeft(CellStyle.BORDER_THIN); 
     style2.setLeftBorderColor(IndexedColors.GREY_25_PERCENT.getIndex()); 
     style2.setBorderRight(CellStyle.BORDER_THIN); 
     style2.setRightBorderColor(IndexedColors.GREY_25_PERCENT.getIndex()); 
     style2.setBorderTop(IndexedColors.GREY_25_PERCENT.getIndex()); 

     for(int i=0; i< 100 ; i++){ 
      for(int j=0; j< 100; j++){ 
       Cell cell = sheet.createRow(i).createCell(j); 
       cell.setCellStyle(style1); 
      } 
     } 


     CellRangeAddress region = new CellRangeAddress(0, 10, 0, 10); 
     cleanBeforeMergeOnValidCells(sheet, region, style2); 
     sheet.addMergedRegion(region); 

     try { 
      FileOutputStream output = new FileOutputStream("tmp/rapport.xls"); 
      workbook.write(output); 
      output.close(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

    private static void cleanBeforeMergeOnValidCells(Sheet sheet, CellRangeAddress region, CellStyle cellStyle) { 
     for (int rowNum = region.getFirstRow(); rowNum <= region.getLastRow(); rowNum++) { 
      Row row = sheet.getRow(rowNum); 
      if (row == null) { 
       sheet.createRow(rowNum); 
      } 
      for (int colNum = region.getFirstColumn(); colNum <= region.getLastColumn(); colNum++) { 
       Cell currentCell = row.getCell(colNum); 
       if (currentCell == null) { 
        currentCell = row.createCell(colNum); 
       } 

       currentCell.setCellStyle(cellStyle); 

      } 
     } 

    } 
} 

Answer 1

Ich glaube, Sie bedeuten, dass Sie die Rasterlinien nicht brauchen, in diesem Fall verwenden Sie die setDisplayGridlines Methode wie:

sheet.setDisplayGridlines(false);
