If one row won't fit on a page, you need to break it up somehow. And it
sounds like you're setting yourself up for a "640kb ought to be enough
for anyone" problem. You'll always find a bigger dataset somewhere.
So how do you detect when your data is too big? IIRC, there's at least
one way to check for "does my table fit". Lets see... It depends on
what kind of table you're using. Is it a com.itextpdf.text.Table, or a
com.itextpdf.text.pdf.PdfPTable?
Table has isCellsFitPage(), and isTableFitsPage().
PdfPTable has... calculateHeightsFast() getRowHeight(),
getTotalHeight(). PdfPTable also has a couple attributes you can use to
control how iText handles situations like this: setExtendLastRow(),
setSplitRows(), setSplitLate().
Rather than stretching the page (which iText won't let you do after
you've started a given page), you can shrink the text.
if(rowText.length() > TOO_BIG)
rowParagraph.setFont( smallerFont );
You could get relatively fancy and use several different font sizes
depending on just how much text there was. And this would be a good
time to start using a fixed-width font if you can... Take all the
guesswork out of what TOO_BIG will be. Note that there are limits to
how small the font can get before it's illegible. Some document types
have legal restrictions on how small the font can be as well. The "fine
print" can only get so fine.
