答

您将不得不使用 ROWSPAN 。

请参考以下code它：

protected void GridView1_DataBound1(object sender, EventArgs e)
{
  for (int rowIndex = GridView1.Rows.Count - 2;
                                     rowIndex >= 0; rowIndex--)
  {
    GridViewRow gvRow = GridView1.Rows[rowIndex];
    GridViewRow gvPreviousRow = GridView1.Rows[rowIndex + 1];
    for (int cellCount = 0; cellCount < gvRow.Cells.Count;
                                                  cellCount++)
    {
     if (gvRow.Cells[cellCount].Text ==
                            gvPreviousRow.Cells[cellCount].Text)
     {
       if (gvPreviousRow.Cells[cellCount].RowSpan < 2)
       {
         gvRow.Cells[cellCount].RowSpan = 2;
       }
       else
       {
        gvRow.Cells[cellCount].RowSpan =
            gvPreviousRow.Cells[cellCount].RowSpan + 1;
       }
       gvPreviousRow.Cells[cellCount].Visible = false;
    }
   }
}
