After performing tests, it seems that grouped rows/column have some issues. Please use the previous sample project I sent you on “W010 - Liasse Locale 99-02” worksheet.
When I click on the “+” button to visualize grouped rows:
The result is : “+” button become “-”, but it does not expand grouped rows.
The result should be : “+” button become “-” and grouped rows are expanded.
When the grouped row are expanded by default.
I click on “-” button -> grouped rows are correctly collapsed.
Then I click on “+” button to expand grouped rows again.
The result is : rows become visible but column width are not correct (attached screenshot)
The result should be : rows become visible with correct column width
