Hi,
I ran into the following problem, where the bottom table border gets drawn twice if the table has a marginbottom set.
This is sample xml which reproduces the problem using 5.1 & 5.4 versions of aspose.pdf.dll:
The resulting pdf is attached. I also attempted to see if version 6.0 (net4.0) fared any better, but that gave me an error “Cannot find black listed licenses resource. Please report this error to Aspose.”. So I reverted back to 5.4.
