There is a table with the pdf document, and it the iFilter is not providing the text contained with the table. Is this a known issue?

Ok, thanks for that. It does look as if you've found a specific problem with iFilter. (Most people find problems with their text instead).  Are you using iFilter directly, to get a text stream, or are you using with an indexing engine? If it's a text stream, search to see if Mattresses or the letters in it appear elsewhere; ordering issues are not unusual.

we have iFilter installed on Windows server, and we are also using code to extract the text (TextReader)

Please don't make me analyse all that. I wanted just the single word you stated as a problem, Mattresses I think it was. Does it copy/paste correctly to another app or not?

There isn't even such a thing as a table in a PDF. It's just text, arranged in a regular way, that might have lines around it. Nothing to inform the iFilter that something is a table, page header etc. (in most cases). So your text extraction issue isn't specifically table related. Try doing a copy/paste of the table text in Acrobat Reader to see what happens.
