Excel HTML output differences

I have an Excel document.
When I save this file as HTML in Excel the output looks like this:
excelOutput_files.zip (88.2 KB)

Whereas when I save this file as HTML using Aspose, the result looks different, there are some lines missing: asposeOutput.zip (47.0 KB)

Left - Aspose, right - Excel

Here is a sample app that reproduces the behavior:
ExcelTest.zip (384.8 KB)

Let me know if you need any more information.
Thanks

@ManMasterDevelopment,
I have tried this scenario using the latest version of Aspose.Cells but could not observe any issue. Could you please give it a try using the latest version 20.6 and share the feedback? For your reference the output files are attached.

Thank you for quick response.

The files you attached contain exactly the same output as mine. I have used v20.6 as well. You got same result as shown in the attached file - which in our customers’ opinion is not correct.

Aspose - left, Excel - right.

@ManMasterDevelopment,
We have logged the issue as “CELLSNET-47452” in our database for investigations. Once, we will have some news for you, we will update you in this topic.

@ManMasterDevelopment,
Please open the source file and get rid of the grid line in MS-Excel, you will discover that the lines don’t exist.
So the excel output html is not correct. We will not fix it. Can you try it and let us know your feedback.
