I'm having an issue with rendering the tablix with border lines.
Please see attached RDL file, the column between c4 and c5 should be completely empty, but the rendered pptx always has a line. The rendered pdf and word file are correct.
Please let me know if this is a bug or how to correct the issue. I'm using the latest version of Aspose.Slide.
