It looks more like a pixel rounding effect in Acrobat. If you zoom
the PDF in, the effect seemingly diappears. Your file also prints OK.
So my impression is that the background rectangle is correctly sized.
I admit however that the Z-order can be made a bit more friendly: one
should draw all backgrounds first, and all borders afterwards, so that
a background could not overlap the border of another cell. Thank you
for the input; we will consider this as a request for improvement.
If your file is for the print, you need not care: the effect only happens
on the screen. If you are building an electronic document, then
a simple workaround for XEP 3.8 is to specify a uniform border
on every cell. That is, if you restyle the table this way, it would
produce the same visual effect without the overlap problems:
<fo:table border-collapse="separate"
table-layout="fixed"
border="0.1pt solid black">
<fo:table-body>
<fo:table-row>
<fo:table-cell border="0.1pt solid black"> ....
<fo:table-cell border="0.1pt solid black"> ....
</fo:table-row>
<fo:table-row background-color="rgb(221, 221, 221)">
<fo:table-cell border="0.1pt solid black"> ....
<fo:table-cell border="0.1pt solid black"> ....
</fo:table-row>
<fo:table-row>
<fo:table-cell border="0.1pt solid black"> ....
<fo:table-cell border="0.1pt solid black"> ....
</fo:table-row>
</fo:table-body>
</fo:table>
Here, each cell has its own border, that is guaranteed to be drawn
on top of the respective background. This prevents backgrounds from
creeping into nearby cells.
