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);
