Description

在是实体类上通过注解@ExcelProperty(value = {"A","B"})创建出一级表头A和二级表头B，如何使用注解将A设置成字号30，B设置成字号20。如果使用注解@HeadFontStyle(fontHeightInPoints = 30)，会对当前A表头和所有二级表头产生效果

Research direction
Inspect the @HeadFontStyle annotation source to understand its propagation, and consider implementing per level styling via custom CellWriteHandler or overriding the style logic.
