            spreadsheetControl1.BeginUpdate();
            Cell dragCell = spreadsheetControl1.ActiveCell;
            Cell dropCell = spreadsheetControl1.ActiveWorksheet.Cells["B2"];

            int pasteLeftColumnIndex = dropCell.IsMerged ? dropCell.GetMergedRanges()[0].LeftColumnIndex : dropCell.LeftColumnIndex;
            int copyLeftColumnIndex = dragCell.IsMerged ? dragCell.GetMergedRanges()[0].LeftColumnIndex : dragCell.LeftColumnIndex;
            int copyRightColumnIndex = dragCell.IsMerged ? dragCell.GetMergedRanges()[0].RightColumnIndex : dragCell.RightColumnIndex;
            int interval = copyRightColumnIndex - copyLeftColumnIndex + 1;
            bool bTowardMove = copyLeftColumnIndex > pasteLeftColumnIndex;
            string copyFromRangeReferenceA1 = string.Format("{0}1:{1}100", ToName(copyLeftColumnIndex + (bTowardMove ? interval : 0)), ToName(copyRightColumnIndex + (bTowardMove ? interval : 0)));
            string pasteRangeReferenceA1 = string.Format("{0}1:{1}100", ToName(pasteLeftColumnIndex), ToName(pasteLeftColumnIndex + interval));            
            spreadsheetControl1.ActiveWorksheet.Columns.Insert(pasteLeftColumnIndex, interval);

            spreadsheetControl1.ActiveWorksheet.Range[pasteRangeReferenceA1].CopyFrom(spreadsheetControl1.ActiveWorksheet.Range[copyFromRangeReferenceA1]);
            for (int i = pasteLeftColumnIndex, j = copyLeftColumnIndex, k = 0; k < interval; i++, j++, k++)
            {
                spreadsheetControl1.ActiveWorksheet.Columns[i].Width = spreadsheetControl1.ActiveWorksheet.Columns[j].Width;
            }
            spreadsheetControl1.EndUpdate();

由数字转换为Excel中的列字母

        public static int ToIndex(string columnName)
        {
            if (!Regex.IsMatch(columnName.ToUpper(), @"[A-Z]+")) { throw new Exception("invalid parameter"); }

            int index = 0;
            char[] chars = columnName.ToUpper().ToCharArray();
            for (int i = 0; i < chars.Length; i++)
            {
                index += ((int)chars[i] - (int)'A' + 1) * (int)Math.Pow(26, chars.Length - i - 1);
            }
            return index - 1;
        }


        public static string ToName(int index)
        {
            if (index < 0) { throw new Exception("invalid parameter"); }

            List<string> chars = new List<string>();
            do
            {
                if (chars.Count > 0) index--;
                chars.Insert(0, ((char)(index % 26 + (int)'A')).ToString());
                index = (int)((index - index % 26) / 26);
            } while (index > 0);

            return String.Join(string.Empty, chars.ToArray());
        }
