问题
I have tried use the poi to generator excel and build a pivot table in. like the code following.
this is not i want to get. you can see in the result. only month have a filter icon.
but when you select a cell in the pivot table then select the design tab. choose the 'Report Layout' then change to show in outline form the filter will apply to month,group1 and code.
is there any way to use the poi to do the step I described before?

As of your question about the pivot table's outline form, all you needs changing in your code is:
Do not set:
pivotTable.getCTPivotTableDefinition().getPivotFields().getPivotFieldArray(0).setOutline(false);
as this is the wrong place to set outline.
Instead do:
...
pivotTable.getCTPivotTableDefinition().setCompact(false);
pivotTable.getCTPivotTableDefinition().setCompactData(false);
pivotTable.getCTPivotTableDefinition().setOutline(true);
pivotTable.getCTPivotTableDefinition().setOutlineData(true);
...
This switches from compact layout to outline layout.
But your additional XSSFTable code leads to a corrupt Excel file for me because you are setting the auto filter in the sheet instead of in the table. I am using apache poi 4.1.0 and the code for creating a table you are using leads to a warning message when opening the Excel file. Then Excel repairs the file by removing the table. Not sure why this XSSFTable is necessary at all but for completeness here the complete example which works correct using apache poi 4.1.0.
