Hi,
I've met with a problem with thicker table border with number-column-spanned
on FOP 1.0.
The copied text exactly describes the same problem I have.
When zoomed to 100% or 200% in Adobe reader, you can find the thicker line.
What about when you zoom to 800% or higher? Also, does the problem
appear when you print the PDF?
Any idea? Seems like it's a bug of FOP, if so, can anyone fix it or point
the Java file I should go?
It's not a bug of FOP, but down to the use of thin lines on low
resolution devices and how different PDF Viewers handles this.
1px is a very thin line. 1pt should be the minimum really to ensure you
don't see strange affects like this on screen.
Adobe Reader does have some options that you can disable to improve the
way thin lines are drawn at 100% zoom. Ensure the option "Enhance Thin
Lines" is disabled

Copied:
I found that using the attribute number-column-spanned inside a cell
element, I get a bad rendering of the cell border: it gets thicker in the
central section of the border.
