The following code results in the table cells wrapping unexpectedly when saving to PDF. This does not happen when saving to DOCX. It only seems to happen when the font-family is specified on the table cell:
var html = @"
<html>
<body>
<table>
<tr>
<td>
<table>
<tr>
<td style='font-family:Arial;'>Available Funding</td>
<td style='font-family:Arial;'>Shortfall</td>
</tr>
</table>
</td>
</tr>
</table>
</body>
</html>";
var stream = new MemoryStream((System.Text.UnicodeEncoding.UTF8.GetBytes(html)));
Document doc = new Document(stream);
doc.Save("PDFCellWrapTest.pdf");
