Asp.net_Table控件の单元格纵向合并

业务需要，动态生成表，同一列中数据相同的单元格需要合并。

解决方案，创建Table控件处理类，代码如下：

[plain]
/// <summary>表格控件相关操作类
/// </summary>
public static class aspTable
{
    /// <summary>合并行
    /// </summary>
    /// <remarks>版权信息： 2013-06-21 14:20:36</remarks>
    /// <param name="tbl">Table</param>
    /// <param name="startRow">起始行</param>
    /// <param name="endRow">结束行</param>
    /// <param name="colIndex">要合并的列索引</param>
    public static void SetRowSpan(Table tbl, int startRow, int endRow, int colIndex)
    {
        int countRowSpan = 0;
        int spanRow = startRow;
        string spanText = tbl.Rows[startRow].Cells[colIndex].Text;
        for (int rowIndex = startRow; rowIndex <= endRow; rowIndex++)
        {
            string currentText = tbl.Rows[rowIndex].Cells[colIndex].Text;
            //内容是否相同
            if (currentText == spanText)
            {
                countRowSpan++;
                //移除被合并的单元格
                if (rowIndex != spanRow)
                {
                    tbl.Rows[rowIndex].Cells.RemoveAt(colIndex);
                }
            }
            else
            {
                //合并
                tbl.Rows[spanRow].Cells[colIndex].RowSpan = countRowSpan;
                //从此行再向下比较（重置）
                countRowSpan = 0;
                spanRow = rowIndex--;
                spanText = currentText;
            }
        }
        //合并最后一项
        tbl.Rows[spanRow].Cells[colIndex].RowSpan = countRowSpan;

    }

    /// <summary>合并行，支持多列
    /// </summary>
    /// <remarks><SPAN style="FONT-FAMILY: Arial, Helvetica, sans-serif">版权信息： style="FONT-FAMILY: Arial, Helvetica, sans-serif"> 2013-06-21 15:24:34</remarks></SPAN>

    /// <param name="startRow">起始行</param>
    /// <param name="endRow">结束行</param>
    /// <param name="colIndex">要合并的列索引</param>
    public static void SetRowSpans(Table tbl, int startRow, int endRow, params int[] colIndexs)
    {
        ArrayList al = new ArrayList(colIndexs);
        al.Sort();
        for (int i = al.Count - 1; i >= 0; i--)
        {
            SetRowSpan(tbl, startRow, endRow, (int)al[i]);
        }
    }
}

        public static void SetRowSpan(Table tbl, int startRow, int endRow, int colIndex)
        {
            int countRowSpan = 0;
            int spanRow = startRow;
            string spanText = tbl.Rows[startRow].Cells[colIndex].Text;
            for (int rowIndex = startRow; rowIndex <= endRow; rowIndex++)
            {
                string currentText = tbl.Rows[rowIndex].Cells[colIndex].Text;
                //内容是否相同
                if (currentText == spanText)

                    countRowSpan++;
                    //移除被合并的单元格
