[xep-support] how to generate a FO table with a preformatted block of text in one FO table cell

[Nikolai Grigoriev]

Hong,

I have tried several combinations of preformatted text
with fo:table-cell, and could not reproduce the error:
white-space-collapse and linefeed-treatment worked
in all possible cases. Could you please send a complete
sample (either a ready FO file, or an XML source +
an XSL stylesheet) to support at renderx.com so that we
can analyze it? Maybe the problems are in the XSLT part,
not XSL FO...

Best regards,
Nikolai Grigoriev
