Hi
I'm trying to create nested tables where the inner table is supposed to span over two column. The problem is that the data in the inner table (from a DataTable) doesn't span over both columns even though the cell it is located in spans over both columns.
This is my code:
Aspose.Pdf.Table layoutTab = new Aspose.Pdf.Table(sec1);
layoutTab.ColumnWidths = "50% 50%";
layoutTab.ColumnAdjustment = ColumnAdjustmentType.Customized;
layoutTab.Rows.Add().Cells.Add();
layoutTab.Rows[0].Cells[0].ColumnsSpan = 2;

Aspose.Pdf.Table tab1 = new Aspose.Pdf.Table(layoutTab.Rows[0].Cells[0]);
tab1.ColumnWidths = "100%";
tab1.ColumnAdjustment = ColumnAdjustmentType.AutoFitToContent;

tab1.Rows.Add().Cells.Add().Paragraphs.Add(new Aspose.Pdf.Text("hello world"));
           
Aspose.Pdf.Table tab2 = new Aspose.Pdf.Table(tab1.Rows.Add().Cells.Add());
tab2.ImportDataTable(myDT, true, 0, 0);
tab1.Rows[1].Cells[0].Paragraphs.Add(tab2);

layoutTab.Rows[0].Cells[0].Paragraphs.Add(tab1);
sec1.Paragraphs.Add(layoutTab);

Then layoutTab.Rows[0].Cells[0] acctually spans over two cells, but the data in tab2 fits in to the size of only one cell and the second cell is empty.

What am I missing?

Hi,

Thank you for considering Aspose.

I have checked with the following code and it works for me. Please find attached PDF generated by the code below:

[C#]

            Aspose.Pdf.Pdf pdf1 = new Aspose.Pdf.Pdf();
            Aspose.Pdf.Section sec1 = pdf1.Sections.Add();
            Aspose.Pdf.Table layoutTab = new Aspose.Pdf.Table(sec1);
            layoutTab.DefaultCellBorder = new BorderInfo((int)BorderSide.All);
           
            layoutTab.ColumnWidths = "50% 50%";
            layoutTab.ColumnAdjustment = ColumnAdjustmentType.Customized;
            layoutTab.Rows.Add().Cells.Add();
            layoutTab.Rows[0].Cells[0].ColumnsSpan = 2;

            DataTable myDT = new DataTable();
            DataColumn dc = new DataColumn("Col1");
            DataColumn dc1 = new DataColumn("Col2");
            myDT.Columns.Add(dc);
            myDT.Columns.Add(dc1);

            myDT.Rows.Add(new object[] {"00","01" });
            //myDT.Rows.Add(new object[] { "10", "11" });

            Aspose.Pdf.Table tab1 = new Aspose.Pdf.Table(layoutTab.Rows[0].Cells[0]);
            tab1.ColumnWidths = "50% 50%";
            //tab1.ColumnAdjustment = ColumnAdjustmentType.AutoFitToContent;

            tab1.Rows.Add().Cells.Add().Paragraphs.Add(new Aspose.Pdf.Text("hello world"));

            Aspose.Pdf.Table tab2 = new Aspose.Pdf.Table(tab1.Rows.Add().Cells.Add());
            tab2.DefaultCellBorder = new BorderInfo((int)BorderSide.All);
            tab1.DefaultCellBorder = new BorderInfo((int)BorderSide.All);
            tab2.ColumnWidths = "50% 50%";
            tab2.ImportDataTable(myDT, true, 0, 0);
            tab1.Rows[1].Cells[0].Paragraphs.Add(tab2);

            layoutTab.Rows[0].Cells[0].Paragraphs.Add(tab1);
            sec1.Paragraphs.Add(layoutTab);

            pdf1.Save("D:/nested.pdf");

Thanks.

Thanks for a quick reply!

But unfortunately this doesn't work when the data (or columnname) in
    DataColumn dc = new DataColumn("Col1");
is longer, for ex:
    DataColumn dc = new DataColumn("Col1xxxxxxxxxxxxxxxxxxxxxx");
See the attatched pdf.

I've also tried this:
    tab1.ColumnWidths = "100% 100%";
    tab1.ColumnAdjustment = ColumnAdjustmentType.AutoFitToContent;
Then the columns become a bit wider but the nested table still only fit to the first cell.

Thanks,
Sara

Hi,

I have changed the code to some extent and I think I am able to produce the result you want. Kindly check it if this fit to you requirement.If not, then can you please send me a sample Pdf/Image so that I can help you more.

[C#]

Aspose.Pdf.Pdf pdf1 = new Aspose.Pdf.Pdf();

Aspose.Pdf.Section sec1 = pdf1.Sections.Add();

Aspose.Pdf.Table layoutTab = new Aspose.Pdf.Table(sec1);

layoutTab.DefaultCellBorder = new BorderInfo((int)BorderSide.All);

layoutTab.ColumnWidths = "50% 50%";

layoutTab.ColumnAdjustment = ColumnAdjustmentType.Customized;

layoutTab.Rows.Add().Cells.Add();

layoutTab.Rows[0].Cells[0].ColumnsSpan = 2;

DataTable myDT = new DataTable();

DataColumn dc = new DataColumn("Col1xxxxxxxxxxxxxxxxxxxxxxxxxxxxx");

DataColumn dc1 = new DataColumn("Col2");

myDT.Columns.Add(dc);

myDT.Columns.Add(dc1);

myDT.Rows.Add(new object[] { "00", "01" });

//myDT.Rows.Add(new object[] { "10", "11" });

 

Aspose.Pdf.Table tab1 = new Aspose.Pdf.Table(layoutTab.Rows[0].Cells[0]);

tab1.ColumnWidths = "50% 50%";

tab1.ColumnAdjustment = ColumnAdjustmentType.AutoFitToContent;

tab1.Rows.Add().Cells.Add().Paragraphs.Add(new Aspose.Pdf.Text("hello world"));

Aspose.Pdf.Table tab2 = new Aspose.Pdf.Table(tab1.Rows.Add().Cells.Add());

tab2.DefaultCellBorder = new BorderInfo((int)BorderSide.All);

tab1.DefaultCellBorder = new BorderInfo((int)BorderSide.All);

tab2.ColumnWidths = "50% 50%";

tab2.ColumnAdjustment = ColumnAdjustmentType.AutoFitToContent;

tab2.ImportDataTable(myDT, true, 0, 0);

tab1.Rows[0].Cells[0].ColumnsSpan = 2;

tab1.Rows[1].Cells[0].ColumnsSpan = 2;

tab1.Rows[1].Cells[0].Paragraphs.Add(tab2);

layoutTab.Rows[0].Cells[0].Paragraphs.Add(tab1);

sec1.Paragraphs.Add(layoutTab);

pdf1.Save("D:/nested.pdf");

Thanks.

Hi
Sorry.. the problem remains.
I've tried to draw a picture in PowerPoint to show what I want it to look like (first slide) and what the problem with the code is (second slide). I added a column in myDT to make it easier to visualize the problem. Please let me know if it still is unclear.

The text-object has no problem spanning over two columns, but the nested Table seems to have that problem. When I create a Table-object I have to tell in which cell to put it (new Table(Cell)), but I can't do that with the Text-object (new Text()). Do you think that could cause this problem?

I found the column width setting with % does not work for nested table with ColumnSpan. I have logged this issue as PDFNET-3652. As a workaround you can set the column width with points value instead of %.
