There is a bit of a strange table formatting issue when using GroupDocs Conversion and Viewer, where an additional vertical bar is added to the table.
I tested with the latest version 21.10 of both in .NET.
Please see the attached document “CustomXML wrong.docx” and compare it to the “CustomXML wrong.pdf” output.
Word CustomXML.zip (79.3 KB)
I was able to “fix” the issue, by changing the values of the files in “customXML” folder inside the DOCX document using 7-Zip.

But I don’t quite get why the XML content should have this effect on the formatting, so I think it’s a bug.
If you open the document in Word, you will also see no formatting issue.
We would need a fix for Converter and Viewer please.
