Hi Michael,
Thanks for your inquiry. In your case, I suggest you please call Document.UpdateTableLayout method
before saving the document to PDF to solve the shared issue. This
method updates widths of cells and tables in the document according to
their preferred widths and content.
You
do not normally need to call this method as cell and table widths are
maintained automatically. You can call this method before exporting to
PDF (or any other fixed-page format), only in rare cases where you
confirmed that tables appear incorrectly laid out in the output
document. Calling this method might help to correct the output.
Please let us know if you have any more queries.
