Hi Team,

We are using merge document to Merge the 5 document into Single , when doing so at the output of the file we are receiving the border box on docx like shared below if it contains tables structure

We need to hide border box, Kindly advise

Do you merge PDFs into one PDF?
Anyway, please share sample files you merge for further testing.
