JXL--Excel使用笔记

JXL简单使用:

 

1.读Excel文件

Workbook workbook = null;

  try
  {
      workbook = Workbook.getWorkbook(new File(path));
  }
  catch(Exception e)
  {
   System.out.println(e);
  }

Sheet sheet = workbook.getSheet(0);
Cell cell=sheet.getCell(i,j);//读第i列，第j行表格的值
System.out.println(cell.getContents());

对于循环读出可以使用
sheet.getRows();方法得到行数
sheet.getColumns();方法得到列数

 

 

2.写Excel:

Workbook wb = Workbook.getWorkbook(new File(path));


WritableCellFormat wcf = new WritableCellFormat();

book = Workbook.createWorkbook(new File(path, wb);
sheet = book.getSheet(0);

jxl.write.Label name = new jxl.write.Label(i,j,"abc",wcf);//在第i列，第j行写入"abc"值，风格为wcf，如果写入的是数字则使用jxl.write.Number
sheet.addCell(name);
try
   {
    book.write();
    book.close();
   }
   catch(WriteException e){}
   catch(IOException e){}

 

3.单元格风格:

设置边框—
WritableCellFormat wcf = new WritableCellFormat();
wcf.setVerticalAlignment(VerticalAlignment.CENTRE);
wcf.setBorder(Border.RIGHT,BorderLineStyle.THIN);
wcf.setBorder(Border.LEFT,BorderLineStyle.THIN);
wcf.setBorder(Border.BOTTOM,BorderLineStyle.THIN);

合并单元格-
sheet.mergeCells(0,1,0,2)
合并(0,1)、(0,2)两个单元格

设置字体-
WritableFont wf = new WritableFont(WritableFont.ARIAL,12, WritableFont.BOLD, false);
WritableCellFormat wcf = new WritableCellFormat(wf);
以及其它各种单元格样式，如设置背景颜色
都可以通过设置WritableCellFormat来设置

 

注：JXL组件对于公式的支持似乎比Apache的poi好
