Html to PDF conversion : Table rendering

Aspose.Words Product Family
1

Hello,
In my process, I convert some html to .doc & .pdf using Aspose.Words.
I have an issue when converting some table with style "<span style="font-size: small;">border-spacing: 0.7pt;</span>". It leads to the "<span style="font-size: small;">width: 375pt;</span>" style to be ignored, producing a bad pdf in the end.

Here is some code to reproduce the issue (producing the attached pdfs)
“String bug” is a html that reproduce the issue.
“String good” is a html that lead to a correct pdf.
“String bug2” is another html that reproduce the issue with style "<span style="font-size: small;">toto: 0.7pt;</span>".

public static void main(final String... args) throws Exception
{
    final String bug = "<p style=\"margin: 0px 0px 0px 0px; padding-left: 0pt; text-align: center;\">&nbsp;</p><table style=\"width: 375pt; border-spacing: 0.7pt;\" cellspacing=\"1\" cellpadding=\"0\"><tbody><tr><td style=\"padding: 0.75pt; vertical-align: middle;\"><p style=\"margin: 0px 0px 0px 0px; padding-left: 0pt;\"><span style=\"font-family: Arial; font-size: 11pt;\"><strong>BETWEEN:</strong></span></p></td><td style=\"padding: 0.75pt; vertical-align: middle;\"><p style=\"margin: 0px 0px 0px 0px; padding-left: 0pt;\"><span style=\"font-size: 11pt;\"><span style=\"font-family: Arial; background-color: #ffff00;\"><strong>Tenant Name</strong></span><img style=\"-aw-left-pos: 0pt; -aw-rel-hpos: column; -aw-rel-vpos: paragraph; -aw-top-pos: 0pt; -aw-wrap-type: inline;\" src=\"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAA8AAAAPCAYAAAA71pVKAAAACXBIWXMAAA7DAAAOwwHHb6hkAAAAEUlEQVR4nGNgGAWjYBQMIgAAA5MAAZrvkucAAAAASUVORK5CYII =\" alt=\"data:image/gif;base64,R0lGODlhAQABAPABAP///wAAACH5BAEKAAAALAAAAAABAAEAAAICRAEAOw = =\" width=\"15\" height=\"15\"><span style=\"font-family: Arial;\"><strong>&nbsp;</strong></span></span></p></td></tr><tr><td style=\"padding: 0.75pt; vertical-align: middle;\"><p style=\"margin: 0px 0px 0px 0px; padding-left: 0pt;\"><span style=\"font-family: Arial; font-size: 11pt;\">&nbsp;</span></p></td><td style=\"padding: 0.75pt; vertical-align: middle;\"><p style=\"margin: 0px 0px 0px 0px; padding-left: 0pt;\"><span style=\"font-size: 11pt;\"><span style=\"font-family: Arial; background-color: #ffff00;\">Tenant Address</span><br><span style=\"font-family: Arial;\">Vancouver, BC</span><br><span style=\"font-family: Arial; background-color: #ffff00;\">Tenant Postal Code</span><br><br><span style=\"font-family: Arial;\">(as \"Tenant\")</span></span></p></td></tr></tbody></table>";

private static void saveToPdf(final String html, final String out) throws Exception
{
    final com.aspose.words.Document document = new com.aspose.words.Document();
    final DocumentBuilder builder = new DocumentBuilder(document);
    builder.insertHtml(html);

    final DocSaveOptions soDoc = new DocSaveOptions();
    soDoc.setUseAntiAliasing(true);
    soDoc.setUseHighQualityRendering(true);
    document.save(out +".doc", soDoc);

    final PdfSaveOptions soPdf = new PdfSaveOptions();
    soPdf.setTextCompression(PdfTextCompression.NONE);
    soPdf.setUseHighQualityRendering(true);
    soPdf.setUseAntiAliasing(true);
    soPdf.setEmbedFullFonts(false);

    document.save(out +".pdf", soPdf);
}

A very strange thing in this code is that if I remove the “save to doc” part (which seems useless), then the “String good” leads to a bad pdf too…

Can you help me on this ?
