Alignement problems in table with no borders

["Foucault, Sebastien" <Se...@hraccess.com>]

Hello,

Here is the problem I have to deal with.
Using FOP 0.20.5 on the following FO file, I got sometimes wrong
alignements. It seems that these wrong alignements depend on the data
present in each cell of the table.

My questions are the following :
Is this problem known ?
How to overcome it ? I notice that the use of the <border-width,
border-style, border-color> tuple on each cell fixes the problem. But I
cannot use it because I need transparent borders (because in the real
situation there's a background image  which makes the use of
border-color="white" unrelevant).

Regards

You're welcome.

It's a bug, yes.

No issues, other than the text generated could be nicer looking from a
typographical point of view. Kerning manipulates the horizontal
positioning of characters, for example it ensures that for "AV" the "V"
is moved closer to the "A" than it would normally be so the text looks
nicer.

I don't know. I've never managed to allocate the time to find out. I was
happy enough to have a work-around.

Try removing all kerning elements from the font metric XML file and
switching kerning to "no" in the userconfig.xml.
