Or try this approach:
```java
@ExcelProperty(
// Old
// groups = Class<?>[]
// New
groups = Object[]
)
enum SheetGroupView {
BY_MARKER_INTERFACE, // Or BY_TYPE_BASED
BY_STRING_BASED
}
```
Usage example:
```java
FesodSheet.write(fileName)
.head(OrderData.class)
// .view(SheetGroupView.BY_MARKER_INTERFACE, DetailGroup.class)
.group(DetailGroup.class)
.sheet()
.doWrite(dataList);
FesodSheet.write(fileName)
.head(OrderData.class)
// .view(SheetGroupView.BY_STRING_BASED, "base", "detail")
.tag("base", "detail")
.sheet()
.doWrite(dataList);
```
With this design, `SheetGroupView` acts as an explicit switch that
determines how the grouping values should be interpreted.
This approach supporting both marker‑interface grouping and lightweight
string‑based tags. while avoiding the need to introduce multiple annotations.
WDYT? @delei
