XSSFFont不'；不适用于Java POI的所有单元格
我用来应用粗体字体的XSSFFont对象对某些单元格有效，而对其余单元格无效 某些单元格在代码中设置为粗体，但在excel文件中显示为未绑定（粗体按钮在excel中高亮显示，但单元格不粗体），请参见下图 但是，如果我有一些未分类的证券（如40种）（与现金处于同一级别），现金将以粗体格式显示，如下所示。在第一张图中，未分类证券有很多证券（520个） 见下图 我的代码是XSSFFont不'；不适用于Java POI的所有单元格,java,excel,apache-poi,Java,Excel,Apache Poi,我用来应用粗体字体的XSSFFont对象对某些单元格有效，而对其余单元格无效 某些单元格在代码中设置为粗体，但在excel文件中显示为未绑定（粗体按钮在excel中高亮显示，但单元格不粗体），请参见下图 但是，如果我有一些未分类的证券（如40种）（与现金处于同一级别），现金将以粗体格式显示，如下所示。在第一张图中，未分类证券有很多证券（520个） 见下图 我的代码是 private void writeCellToExcel(Workbook workBook, ExportExcelCel
