Bug in WPAT_BorderWidthB ?

Hi,

following code to draw borderlines in a table:

if i set value to 0 a fine line is drawn, from 1 to 7 there is no line and over 7 the line is always drawn.

i think it is a bug, linewidth -> 0 should not draw a borderline, or?

Ciao

Thank you for this tip, i have to hide borders instead set the width to 0...

Ciao

P.S.
if "0 means usually hairline, thats the smallest line possible on a device", why is with a greater value (1 to 7) no border visible?
