How to create a Table having Cells spanning multiple Rows or Columns

Hi there,
I would like to create a table using Aspose.Words API which might have cells spanning more than one row or column. HTML code of these types of tables can be described as follows:

<table>
  <tr>
     <td rowspan="2" width="30%">This is cell spans two rows</td>
     <td valign="top" width="45%">This is just a regular cell</td>
     <td valign="top" width="45%" colspan="2">This cell spans two columns</td>
  </tr>
  <tr>
      <td> Second Row Cell number 1</td>
      <td> Second Row Cell number 2</td>
      <td> Second Row Cell number 3</td>
  </tr>
</table>

Now using Aspose.Words I can ofcourse create a table using insertCell() method of DocumentBuilder. I can set style/formatting to the content of the cells, but I could not find any method in any class like RowFormat or **CellFormat **using which I can write code to generate table like above. Please let me know if Aspose.Words have any solution to resolve this issue.
One more issue is with the width of a table cell. Is there anyways we can set the width of a table cell that is specified in percentage just like the above example using Aspose.Words? I can only find the method called setWidth from CellFormat class. But this only accepts double valued parameters in points. As I am trying to convert HTML to Word Document, I dont know what would be the exact width of my table cells in points. So please check this issue as well.
Thanks a lot.

Hi
Thanks for your inquiry. I think that you should use CellFormat.verticalMerge and CellFormat.HorizontalMerge. For example see the following code in C#.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
PageSetup setup = builder.CurrentSection.PageSetup; //get width of page
double width = setup.PageWidth - setup.LeftMargin - setup.RightMargin;
builder.CellFormat.Borders.LineStyle = LineStyle.Double; //set borders linestyle
builder.CellFormat.VerticalAlignment = CellVerticalAlignment.Center; //set vertical alignment
builder.InsertCell(); //insert first cell
builder.CellFormat.VerticalMerge = CellMerge.First; //merge cells verticaly
builder.CellFormat.Width = width * 0.3; //set width of cell = 30%
builder.Write("This is cell spans two rows"); //insert text
builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.None;
builder.CellFormat.Width = width * 0.35; //set width of cell = 35%
builder.Write("This is just a regular cell");
builder.InsertCell();
builder.CellFormat.HorizontalMerge = CellMerge.First; //merge cells horizontaly
builder.CellFormat.Width = width * 0.35 / 2; //set width of cell = 17.5%
builder.Write("This cell spans two columns");
builder.InsertCell();
builder.CellFormat.HorizontalMerge = CellMerge.Previous;
builder.CellFormat.Width = width * 0.35 / 2; //set width of cell = 17.5%
builder.EndRow(); //end firs row
builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.Previous;
builder.CellFormat.HorizontalMerge = CellMerge.None;
builder.CellFormat.Width = width * 0.3;
builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.None;
builder.CellFormat.Width = width * 0.35;
builder.Write("Second Row Cell number 1");
builder.InsertCell();
builder.CellFormat.HorizontalMerge = CellMerge.None;
builder.CellFormat.Width = width * 0.35 / 2;
builder.Write("Second Row Cell number 2");
builder.InsertCell();
builder.CellFormat.Width = width * 0.35 / 2;
builder.Write("Second Row Cell number 3");
builder.EndRow();
builder.EndTable();
doc.Save("out.doc");

I hope that this will help you.
Best regards.
