Border has extra width when using ColumnSpan

Hi! I have an issue with the border having extra width when using ColumnSpan. The version of Aspose I am using is 8.0. I have attached the resulting PDF. Here is the code:


public static void BordrExtraWidth()
{
Pdf pdf = new Pdf();
pdf.CompressionLevel = 6;
Section section = new Section(pdf);
pdf.Sections.Add(section);

section.Paragraphs.Add(new Text(“In all tables below, the LineWidth of the Top border is always specified as 2. #$NL” +
“We can also see that the right border overlaps the top border which is pretty ugly/annoying. #$NL " +
“When the thick border appears, look closely and you will see it overlaps on the left. #$NL #$NL”));

section.Paragraphs.Add(new Text(“Column span of 4”));
Table table = new Table();
table.ColumnWidths = “10% 20% 10% 5% 10% 20% 10% 5% 10%”;
table.RepeatingRows = 2;

AddCellWithBackgroundAndBorder(row, “Year”, rowSpan: 2);
AddCellWithBackgroundAndBorder(row, “3/4 thin border”, colSpan: 4);
AddCellWithBackgroundAndBorder(row, “Thick border! Why?”, colSpan: 4);

Hi there,


Thanks for your inquiry. I've managed to reproduce the issue at my end and logged it as PDFNEWNET-35320 in our bug tracking system for further investigation and resolution. You will be notified via this thread as soon as it is resolved.


Sorry for the inconvenience faced.


Best Regards,

Hi,


Thanks for your patience.

I am pleased to share that the issue reported earlier has been resolved. Please try using the following code snippet based on new DOM approach to generate correct output. For your reference, I have also attached the resultant PDF generated over my end using upcoming release of Aspose.Pdf for .NET 8.2.0.
