With smooth line art turned on, Acrobat Reader smoothens table frames. I
don't know whether it is a native Windows thing or an Adobe's smart
approach, but rectangular shapes are not smoothed, while other shapes do.
The border on the left, while exactly of the same width, is not
rectangular (the line, not the frame), it has an obtuse and a sharp angle
at a joint. The border on the right is a rectangle, because vertical
borders are of zero width.

Thus, the left-hand horizontal border appears with smooth edges of the
polygon, and the right-hand border is with sharp edges. With big
magnifications and with line art turned off they are exactly the same
(they are exactly the same in the PDF, too, exactly 1 pt, turn compression
off and you'll see).

This is a Windows specific nonsense: renderers on all other platforms
demonstrate consistant smoothing of all shapes.
