Is it possible to do multi-level grouping like in the attached spreadsheet? I also included a sample dataset.
I tried using Cells.GroupRows, but it doesn’t seem to work correctly when going into the second level of grouping
Hi Varun,
Thank you for contacting Aspose support.
You can achieve your goal using the Cells.GroupRows method alone. If you wish to create a multi-level grouping, that is; grouping with in grouping, all you have to do is to create a larger group lets say from row 2 to 17 and then create a smaller group referencing the rows between the previously assigned range, such as 3 to 8. Please check the below provided code snippet for your reference.
C#
//Accessing the cells of first worksheet
var cells = worksheet.Cells;
//Creating a larger group spanning between row 2 and row 17
cells.GroupRows(1, 16, false);
//Creating a smaller group spanning between row 3 and row 8
cells.GroupRows(2, 7, false);
