POI 怎么设置Excel整列的CellStyle

// 生成一个样式
    HSSFCellStyle style = workbook.createCellStyle();

// 设置这些样式
    style.setFillForegroundColor(HSSFColor.WHITE.index);
    style.setFillPattern(FillPatternType.SOLID_FOREGROUND);
    style.setBorderBottom(BorderStyle.THIN);
    style.setBorderLeft(BorderStyle.THIN);
    style.setBorderRight(BorderStyle.THIN);
    style.setBorderTop(BorderStyle.THIN);
    style.setAlignment(HorizontalAlignment.CENTER);

DataFormat fmt = workbook.createDataFormat();
CellStyle textStyle = workbook.createCellStyle();
textStyle.setDataFormat(fmt.getFormat("@"));
worksheet.setDefaultColumnStyle(0, textStyle);
