使用WritableCellFormat 的setWrap(true)可以设成自动换行，然后再用WritableSheet的setRowView设置行的高度，setColumnView设置列的宽度
行高和列宽
WritableSheet.setRowView(int i,int height);
作用是指定第i+1行的高度，比如：
//将第一行的高度设为200
sheet.setRowView(0,200);
WritableSheet.setColumnView(int i,int width);
作用是指定第i+1列的宽度，比如：
//将第一列的宽度设为30
sheet.setColumnView(0,30);
单元格居中
Label label=new Label(column,row,labelValue);
WritableCellFormat cellFormat=new WritableCellFormat();
cellFormat.setAlignment(jxl.format.Alignment.CENTER);
label.setCellFormat(cellFormat);
sheetWrite.addCell(label);
WritableCellFormat headerFormat = new WritableCellFormat();
//水平居中对齐
headerFormat.setAlignment(Alignment.CENTRE);
//竖直方向居中对齐
headerFormat.setVerticalAlignment
(VerticalAlignment.CENTRE);
//建立标签，参数依次为：列索引、行索引、内容、格式
Label seqLabel = new Label(0, 0, "序号", headerFormat);
//增加单元格
sheet.addCell(seqLabel);
//合并单元格，参数依次为：列索引、行索引、列索引+需要合并
的列的个数、行索引+需要合并的行的个数
sheet.mergeCells(0, 0, 0, 1);
//设置单元格宽度，以字符为单位
sheet.setColumnView(0, "序号".length() + 10);
Label basicInfoLabel = new Label(1, 0, "基本信息",
headerFormat);
sheet.addCell(basicInfoLabel);
sheet.mergeCells(1, 0, 3, 0);//合并垮了3行。
sheet.mergeCells(1, 1, 1, 3);//合并垮了3列。
label = new Label(0, 1, "苹果”);
sheet.mergeCells(0,1, 0, 3- 1);//合并垮了3列。
WritableCellFormat cellFormat = new WritableCellFormat();
cellFormat.setVerticalAlignment(VerticalAlignment.CENTRE);
// 垂直居中
label.setCellFormat(cellFormat);
sheet.addCell(label);
