I created a table in Word and added a 2 1/4 pt white border. The table also has shading which was applied to the cells. The table looks fine in Word. However, when I save the document as a PDF, the borders appear in PDF with a small notch, as if a portion of the border does not extend far enough alongside the cell.
Screenshot of PDF output:
I've tried changing the border width, but it makes no difference. With a 3 pt border, I get the same result. All cell margins are the same. "Allow spacing between cells" is NOT checked for any cells.
UPDATE:
In Adobe Acrobat, if I go to Edit > Preferences > Page Display > Rendering and uncheck "Enhance thin lines," the effect almost disappears. Almost.
When I print, it's nearly impossible to see the change in border width. This is a report that will be shared electronically, but at least the print version will be acceptable.
