I have the next problem:
I need merge the rows with the same value for this table:
This table is in a GridView, and I realize the method that merge that rows
private void AgruparGridView(GridViewRowCollection rows, int indiceInicial, int totalCeldasAgrupar)
{
//Si no hay celdas a agrupar no realiza ninguna acción
if (totalCeldasAgrupar == 0)
return;
int i, count = 1;
ArrayList lst = new ArrayList();
// Los elementos del gridview son llenados en la lista.
lst.Add(rows[0]);
var ctrl = rows[0].Cells[indiceInicial];
//Recorrer los registros que se tengan para agrupar
for (i = 1; i < rows.Count; i++)
{
TableCell nextCell = rows[i].Cells[indiceInicial];
if (ctrl.Text == nextCell.Text)
{
count++;
nextCell.Visible = false;
lst.Add(rows[i]);
}
else
{
if (count > 1)
{
ctrl.RowSpan = count;
AgruparGridView(new GridViewRowCollection(lst), indiceInicial + 1, totalCeldasAgrupar - 1);
}
count = 1;
lst.Clear();
ctrl = rows[i].Cells[indiceInicial];
lst.Add(rows[i]);
}
}
if (count > 1)
{
ctrl.RowSpan = count;
AgruparGridView(new GridViewRowCollection(lst), indiceInicial + 1, totalCeldasAgrupar - 1);
}
count = 1;
lst.Clear();
}
I need realize the same result on a PDF Report with iTextSharp, but I haven’t idea for this process.
The fragment of the code that builds this section is this:
public PdfPTable Tablas(int TipoSeccion, int TipoDoc, int ClaveEntidad, int ClaveSubSis, string descripcion)
{
PDFEvents oPDFEvents = new PDFEvents();
string sError = string.Empty;
int columns = 1;
int i = 0;
DataSet _DatosTabla = null;
PdfPTable Table;
PdfPCell CeldaNoBorde = new PdfPCell(CeldasSinBorde("", 1, 1, 4, 255, 255, 255));
#region PerfilesDOCENTE
#region Tipo3
if (TipoSeccion == 3)
{
columns = 3;
Table = new PdfPTable(columns);
Table.WidthPercentage = 80;
float[] widhts = new float[] { 15, 50 };
//Header Superior
if (this.TipoSeccionOriginal == 3 || this.TipoSeccionOriginal==0)
{
Table.AddCell(Celdas("ASIGNATURAS POR EXAMEN DISCIPLINAR PARA FUNCIONES DOCENTES", 2, 3, 8, 238, 233, 233));
Table.AddCell(Celdas("Área disciplinar", 3, 1, 10, 238, 233, 233));
Table.AddCell(Celdas("Asignatura", 3, 1, 10, 238, 233, 233));
Table.AddCell(Celdas("Evaluación Disciplinar", 3, 1, 10, 238, 233, 233));
_DatosTabla = DameDatosTablaPerfilesTelebach(ClaveEntidad, ClaveSubSis);
}
else
{
Table.AddCell(Celdas("ASIGNATURAS A CONCURSO PARA FUNCIONES TÉCNICO DOCENTES", 1, 2, 8, 238, 233, 233));
Table.AddCell(Celdas("Evaluación", 2, 1, 10, 238, 233, 233));
Table.AddCell(Celdas("Asignaturas", 2, 1, 10, 238, 233, 233));
_DatosTabla = DameDatosTablaPerfiles(TipoDoc, ClaveEntidad, ClaveSubSis, true);
}
if (_DatosTabla != null)
{
while (i < _DatosTabla.Tables[0].Rows.Count)
{
Table.AddCell(oPDFEvents.FontPhrase(_DatosTabla.Tables[0].Rows[i][0].ToString(), 10));
Table.AddCell(oPDFEvents.FontPhrase(_DatosTabla.Tables[0].Rows[i][1].ToString(), 10));
Table.AddCell(oPDFEvents.FontPhrase(_DatosTabla.Tables[0].Rows[i][2].ToString(), 10));
i = i + 1;
}
}
return Table;
}
My result is this
Sorry for my bad english!!
Thank you for you attention!

Method 1
You need to set Rowspan = n on the appropriate PdfPCell and omit adding the next n-1 cells in that column. Here’s an example that first builds a regular 3×3 table. Cells are marked row,column. Then a table is built with Rowspan = 3 on the first cell. The fourth (2,1) and seventh (3,1) cell are not added.
Document doc = new Document();
PdfWriter writer =
PdfWriter.GetInstance(doc, new FileStream("tables.pdf", FileMode.Create));
doc.Open();
doc.Add(new Paragraph("Table without rowspan:"));
PdfPTable table = new PdfPTable(3);
table.SpacingBefore = 10;
table.AddCell(new PdfPCell(new Phrase("1,1")));
table.AddCell(new PdfPCell(new Phrase("1,2")));
table.AddCell(new PdfPCell(new Phrase("1,3")));
table.AddCell(new PdfPCell(new Phrase("2,1")));
table.AddCell(new PdfPCell(new Phrase("2,2")));
table.AddCell(new PdfPCell(new Phrase("2,3")));
table.AddCell(new PdfPCell(new Phrase("3,1")));
table.AddCell(new PdfPCell(new Phrase("3,2")));
table.AddCell(new PdfPCell(new Phrase("3,3")));
doc.Add(table);
doc.Add(new Paragraph("Table with rowspan 3 on first cell:"));
PdfPTable tableWithRowspan = new PdfPTable(3);
tableWithRowspan.SpacingBefore = 10;
PdfPCell cellWithRowspan = new PdfPCell(new Phrase("1,1"));
// The first cell spans 3 rows
cellWithRowspan.Rowspan = 3;
tableWithRowspan.AddCell(cellWithRowspan);
tableWithRowspan.AddCell(new PdfPCell(new Phrase("1,2")));
tableWithRowspan.AddCell(new PdfPCell(new Phrase("1,3")));
// Cell 2,1 does not exist
tableWithRowspan.AddCell(new PdfPCell(new Phrase("2,2")));
tableWithRowspan.AddCell(new PdfPCell(new Phrase("2,3")));
// Cell 3,1 does not exist
tableWithRowspan.AddCell(new PdfPCell(new Phrase("3,2")));
tableWithRowspan.AddCell(new PdfPCell(new Phrase("3,3")));
doc.Add(tableWithRowspan);
doc.Close();
