I am using Aspose.Cells v18.104.22.168.
In case of tables and ranges, wrong background color appears when converting them to any format - Pdf, Image and Html. The issue appears for all these formats.
This is a break in v22.214.171.124. as compared to v8.6.3.
I have attached the Excel file, Html, PNG and PDF output, and Sample code used to generate the output in attachments.rar
Can you please analyse this issue.
