Hello @Prashanth_Allamreddy ,
Here is the working example with empty cells: Code Snippet
It sounds like you’re experiencing problems with missing borders for empty cells, despite having set properties like style and stubCells.
To help you with this issue, could you please provide an example where the problem is visible? This will allow us to track the style conversion during the export process.
Additionally, do you have any special styles applied to the rows that contain values, or to the adjacent rows? Understanding your styling setup could help us identify why the borders are missing.
