在CODE上查看代码片派生到我的代码片
public static List parse(File file) {    
    List excelValueList = new ArrayList();    
    if (file.exists() && file.canRead()    
            && (file.getName().lastIndexOf(".xls") >= 1)) {    
        Workbook workbook = null;    
        try {    
            workbook = Workbook.getWorkbook(file);    
            Sheet sheet = workbook.getSheet(0);    
            int row = sheet.getRows();    
            int col = sheet.getColumns();    
            for (int r = 0; r < row; r++) {    
                String[] rowValue = new String[col];    
                for (int c = 0; c < col; c++) {    
                    rowValue[c] = sheet.getCell(c, r).getContents() != null   sheet    
                            .getCell(c, r).getContents()    
                            : "";    
                }    
                excelValueList.add(rowValue);    
            }    
        } catch (BiffException e) {
