下面的这个方法因为dataset里的数据有1900多行，导致整个word生成失败， 这个方法的主要功能是，添加行数据到表格，并将数据复制到head.doc模板，在另存为一个新的word文件。红色部分是调试的时候，一直没有执行完的地方。（实际上数据是生成完了的，但都是在临时文件里。。。具体可能要清楚的朋友的才能明白），请大家提点建议，谢谢！

            cls = new Word.ApplicationClass();

                  ref missing, ref missing, ref missing, ref missing,
                  ref missing, ref missing, ref missing, ref missing,
                  ref missing, ref missing, ref missing, ref missing);

                table = doc.Tables[1];
                //object newRow = table.Rows[1];
                for (int i = 0; i < addRowCount; i++)
                {
                    Word.Row row = table.Rows[1];

                    DataRow dr = ds.Tables[0].Rows[i];

                    row.Cells[1].Range.Text = dr[0].ToString();
                    row.Cells[2].Range.Text = dr[1].ToString();
