GridView合并行

public static void MergeRows(GridView gvw, int sCol, int eCol)//gvw 需要合并的GridView，sCol要合并开始列（从0开始），eCol要合并的结束列 
    {
        for (int rowIndex = gvw.Rows.Count - 2; rowIndex >= 0; rowIndex--)
        {
            GridViewRow row = gvw.Rows[rowIndex];

            GridViewRow previousRow = gvw.Rows[rowIndex + 1];

            for (int i = sCol; i < eCol + 1; i++)
            {
                if (row.Cells[i].Text != "" && row.Cells[i].Text != " ")
                {
                    if (row.Cells[i].Text == previousRow.Cells[i].Text)
                    {
                        row.Cells[i].RowSpan = previousRow.Cells[i].RowSpan < 1 ? 2 : previousRow.Cells[i].RowSpan + 1;

                        previousRow.Cells[i].Visible = false;
                    }
                }
            }
        }
    }

很简单的代码
