Question

我有下一个问题：

我需要合并此表的相同值的行：

这个表在GridView中，我意识到合并行的方法

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();
}

我需要在使用iTextSharp的PDF报告中实现相同的结果，但我不知道这个过程。

构建此部分的代码片段是：

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;
        }

我的结果就是这个

您需要在相应的PdfPCell上设置n-1，并省略在该列中添加下一个Rowspan = 3单元格。这是一个首先构建常规3x3表的示例。单元格标记为行，列。然后在第一个单元格上使用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();构建一个表。第四个（ 2,1 ）和第七个（ 3,1 ）单元格未添加。

perl -pe '/\((\d+) members?\)/ && do {$close = $.+$1; s/$/OPEN_TAG/;}; $.==$close && do {s/$/CLOSE_TAG/};' input-file

结果：

如何在ASP.NET和C＃中使用iTextSharp在PDF中合并具有相同值的行？
