Wrong border color for merged cells

Aspose.Cells Product Family
1

Hello Aspose team,

We are currently experiencing an issue with Aspose.Cells starting from version 18.8.0 and continuing through the latest version, 25.5.0, when using the .NET Framework 4.8.

Specifically, when we use the InsertRange method to insert a range of cells into a customer’s sample document, the border color for merged cells appears incorrect.

Please refer to the attached simplified sample code (InsertRangeSampleApp.zip ) to reproduce the issue. In the root folder, there is a truncated customer file named “Original.xlsx.” We would like to draw your attention to the Right Border color of cell B2 both before and after the insertion.

We have also included screenshots for clarification:

As you can see in the screenshots, the Right Border color in cell B2 incorrectly applies the color from the last merged cell (D2/E2), which is not expected behavior. In contrast, the Right Border color in cell C2 does not apply this color.

We have been encountering this behavior since version 18.8.0 and it persists in the latest version, 25.5.0.

Thank you for your attention to this matter.
