合并GridView中的单元格

有时我们需要将GridView中的前几列显示相同的数据合并起来，让表格看起来有分组的感觉。

 int i, j, k, intSpan;//i开始行,j比较行,k列数,intSpan相同行数
        string strTemp;//保存开始行的值
        if (PressCrackData.Rows.Count > 0)
        ...{
            for (k = 1; k < 2; k++)
            ...{
                for (i = 0; i <= PressCrackData.Rows.Count - 1; i++)
                ...{
                    intSpan = 1;
                    strTemp = PressCrackData.Rows[i].Cells[k].Text;
                    for (j = i + 1; j <= PressCrackData.Rows.Count - 1; j++)
                    ...{
                        if (string.Compare(strTemp, PressCrackData.Rows[j].Cells[k].Text) == 0)
                        ...{
                            intSpan += 1;
                            PressCrackData.Rows[i].Cells[k].RowSpan = intSpan;
                            PressCrackData.Rows[j].Cells[k].Visible = false;
                        }
                        else
                        ...{
                            j = PressCrackData.Rows.Count - 1;
                        }

                    }
                    i += intSpan - 1;
                }
            }
        }

 

PressCrackData为GridView
