Converting HTML to PDF - merged cells


We’re using your product to convert HTML to various formats. We’re having a problem with the attached document Template.HTML.

The C# code we’re using:

static void DoPDF(string[] args)
using (MemoryStream inStream = new MemoryStream(File.ReadAllBytes(@“C:\Temp\Template.html”)))
using (MemoryStream outStream = new MemoryStream())
Document d = new Document(inStream);

// workaround for bug Issue with Colspan and HTML to PDF

// we use our own enum value so we’re not tied to using Aspose for this service, but we need to convert between the enums
SaveFormat saveFormat = SaveFormat.Pdf;

d.Save(outStream, saveFormat);

File.WriteAllBytes(@“C:\Temp\out.pdf”, outStream.ToArray());


/// Remove content from merged cells.

public static void RemoveContentFromMergedCells(Document doc)
// Get collection of cells in the docuemnt.
NodeCollection cells = doc.GetChildNodes(NodeType.Cell, true);

foreach (Aspose.Words.Tables.Cell cell in cells)
// Check whether cell is merged with previouse.
if (cell.CellFormat.HorizontalMerge == CellMerge.Previous ||
cell.CellFormat.VerticalMerge == CellMerge.Previous)
// Remove content from the cell.


The main problem is with the merged Cells that are not closed properly but with some weird diagonal lines.

Can you explain and provide a fix or a workaround?

Thank you,

Hi Mihai,

Our apologises for the late reply. I have taken a look at your document but was unable to reproduce the issue using the latest version of Aspose.Words 9.2 avaliable from here.

Also please note it appears that the bug that you were originally calling the method to work around does not appear in the latest version so the RemoveContentFromMergedCells(d); call is not needed.
