Thanks!

Hi Bea,

Thanks for sharing the detail. In your document, the width of table is 474.75 pt which is less than default page size. However, due to the large size image in your table, it is rendering outside the page.

In this case, we suggest you please calculate the table’s width using Aspose.Words.Layout APIs. Please use the following code example to get the desired output. Hope this helps you.

Aspose.Email.Mail.MailMessage msg = Aspose.Email.Mail.MailMessage.Load(MyDir + "EMail_2016-78.msg");
MemoryStream StreamMHT = new MemoryStream();
msg.Save(StreamMHT);
msg.Save(MyDir + "Out.mhtml");
StreamMHT.Position = 0;
Aspose.Words.LoadOptions lLoadOptions = new Aspose.Words.LoadOptions();
lLoadOptions.LoadFormat = Aspose.Words.LoadFormat.Mhtml;
Document doc = new Document(StreamMHT);
Table table = (Table)doc.GetChild(NodeType.Table, 0, true);
// Calculate the table's width
// Insert bookmark in the last cell of table's first row and 
// get its position using Aspose.Words.Layout APIs
Paragraph p = table.FirstRow.LastCell.LastParagraph;
p.AppendChild(new BookmarkStart(doc, "bookmark"));
p.AppendChild(new BookmarkEnd(doc, "bookmark"));
ParagraphAlignment palignment = p.ParagraphFormat.Alignment;
p.ParagraphFormat.Alignment = ParagraphAlignment.Right;
Bookmark bm = doc.Range.Bookmarks["bookmark"];
LayoutCollector collector = new LayoutCollector(doc);
LayoutEnumerator layoutEnumerator = new LayoutEnumerator(doc);
var renderObject = collector.GetEntity(bm.BookmarkStart);
layoutEnumerator.Current = renderObject;
RectangleF location1 = layoutEnumerator.Rectangle;
layoutEnumerator.MoveParent(LayoutEntityType.Row);
RectangleF location2 = layoutEnumerator.Rectangle;
double tablewidth = location1.X - location2.X;
if (tablewidth > doc.FirstSection.PageSetup.PageWidth)
{
    bm.Remove();
    p.ParagraphFormat.Alignment = palignment;
    table.PreferredWidth = PreferredWidth.FromPercent(100);
    table.AutoFit(AutoFitBehavior.AutoFitToWindow);
}
doc.Save(MyDir + "Out v16.12.0.pdf");

Thanks for the reply.

How can I iterate through ALL tables in a document? And do I really need the Bookmarks and LayoutEnumerator?

Can’t I just get the table width and compare it to the page width?

Ok, I see…there is reallly really NO way to get the actual width of a table??

Hi Bea,

Thanks for your inquiry. You can get the table’s width using Aspose.Words. Please refer to the following article:
Specifying Table and Cell Widths

In your case, the table renders outside the page due to its size. Please open the output MHTML in MS Word and remove the big size image. You will then get the exact table width. In your case, you need to calculate the table’s width as shown in my previous reply.

Please let us know if you have any more queries.

I tried your code solution - I changed the code to a more generic approach, it works BUT only if I update the page layout of the document:

doc.UpdatePageLayout();

Hi Bea,

Thanks for your feedback. It is nice to hear from you that your problem has been solved. In your case, you need to call Document.UpdatePageLayout method before saving document to PDF.

Please let us know if you have any more queries.
