ApachePOI如何使用java在excel中包装文本

Question

我需要使用java将文本包装到描述列中 我用的是时尚。setWrapText（）；它不起作用

public CellStyle getDefaultCellStyle(Workbook workbook, boolean isAlignCenter) {
    CellStyle style = workbook.createCellStyle();
    style.setBorderTop(BorderStyle.THIN);
    style.setBorderBottom(BorderStyle.THIN);
    style.setBorderLeft(BorderStyle.THIN);
    style.setBorderRight(BorderStyle.THIN);
    style.setWrapText(true);

    if (isAlignCenter)
        style.setAlignment(HorizontalAlignment.CENTER);

    return style;
}
