C#合并excel单元格,操作合并后的单元格，先合并行，再和并列或者先合并列再合并行。

我想合并excel单元格，但不光是行合并，或是列合并，而是其中既包含行合并又包含列合并（就是把列合并的单元格再行合并，反过来也是），比如我想把前三行合并成一个单元格怎么办？（前三行已经是列合并后的单元格啦）有高手么？指点一下~~

DataTable dt = ds.Tables[0];
//获取excel的文件名称（Guid是一个全球表示，使excel的文件名不同）

//初始化excel对象
Excel.Application excel = new Excel.ApplicationClass();
//Excel.Application excel1 = new Excel.ApplicationClass();
//定义列
int rowIndex = 5;
//定义行
int colIndex = 0;
//开始添加
excel.Application.Workbooks.Add(true);
Excel.Range range = excel.get_Range(excel.Cells[1, 1], excel.Cells[2, 1]);
