能不能以第一列为首要，第1列的合并为第2列合并的基础。如图cc这个值，既属于A又属于B且相邻在一起，两个值需要以第一列为标准进行区分。请阿非大哥再来看看！有兴趣的也一起来看看，继续拓展下！
如图：

试试这个,测试过可以用
int row = 0;
for (int i = 1; i < gv.Rows.Count; i++)
{
if (gv.Rows[i].Cells[0].Text == gv.Rows[i - 1].Cells[0].Text)
{
//if (gv.Rows[row].Cells[1].RowSpan == 0)
//{
// gv.Rows[row].Cells[0].RowSpan++;
//}
gv.Rows[row].Cells[0].RowSpan++;
gv.Rows[i].Cells[0].Visible = false;
}
else
{
gv.Rows[row].Cells[0].RowSpan++;
row = i;
}
}
gv.Rows[row].Cells[0].RowSpan++;
row = 0;
for (int i = 1; i < gv.Rows.Count; i++)
{
if (gv.Rows[i].Cells[1].Text == gv.Rows[i - 1].Cells[1].Text && gv.Rows[i].Cells[0].RowSpan == 0 && gv.Rows[i].Cells[0].Visible == false)
{
//if (gv.Rows[row].Cells[1].RowSpan == 0)
//{
// gv.Rows[row].Cells[0].RowSpan++;
//}
gv.Rows[row].Cells[1].RowSpan++;
gv.Rows[i].Cells[1].Visible = false;
}
else if (gv.Rows[i].Cells[1].Text == gv.Rows[i - 1].Cells[1].Text && gv.Rows[i].Cells[0].RowSpan > 0 && gv.Rows[i].Cells[0].Visible == true)
{
gv.Rows[row].Cells[1].RowSpan++;
row = i;
}
else
{
gv.Rows[row].Cells[1].RowSpan++;
row = i;
}
}
gv.Rows[row].Cells[1].RowSpan++;
