jxl或者POI里是否有对excel超链接的处理

看了POI文档，找到一个LinkedDataFormulaField 和LinkedDataRecord，jxl文档里有 Hyperlink,现在我想对一个excel中的一组sheet做一个索引，方便查找每张sheet,请问这里有没有人做过，看了文档之后还是没有什么头绪，请高人指教！
已经解决了:

String outputFile="D:/导出接口.xls";
try
{
Workbook wb=Workbook.getWorkbook(new File(outputFile)); //Excel获得文件
//打开一个文件的副本，并且指定数据写回到原文件
WritableWorkbook book=Workbook.createWorkbook(new File(outputFile),wb); 
WritableSheet sheet=book.createSheet("导出目标",0); //添加一个工作表
String[] oriSheetNames=wb.getSheetNames();  //获得源excel文件中的所有sheet名称
 for(int i=0;i<book.getNumberOfSheets();i++)
 {
    sheet.addCell(new Label(0,i+1,String.valueOf(i+1)));  //第一列写入编号
/**
* public WritableHyperlink(int col,int row,java.lang.String desc,WritableSheet sheet,int destcol,int destrow)
* Constructs a hyperlink to some cells within this workbook 
* col - the column containing this hyperlink
* row - the row containing this hyperlink
* desc - the cell contents for this hyperlink
* sheet - the sheet containing the cells to be linked to
* destcol - the column number of the first destination linked cell
* destrow - the row number of the first destination linked cell
* */
sheet.addHyperlink(new WritableHyperlink(1,i+1,oriSheetNames[i],book.getSheet(oriSheetNames[i]),0,0));
book.write();
book.close();
wb.close();
}catch(IOException e)
{
	System.out.println("异常: "+e);
}
catch(BiffException e)
{
	System.out.println("异常: "+e);
}
catch(RowsExceededException e)
{
	System.out.println("异常: "+e);
}
catch(WriteException e)
{
	System.out.println("异常: "+e);
}

借楼主地一下，一直有一个问题没解决，就是如何设置一个cell的宽和高？有谁知道
