通过递归填充单元格达到矩形范围的同行同列自动选择，接下来就可以合并所选择的单元格：

计算最大宽度和最大高度，并且使左上角的单元格等于最大宽高，以实现合并效果：

            //计算最大宽度
            double w = borderFirst.Width;
            for (int i = 0; i < bors.Count; i++)

            }

            //计算最大高度
            double h = borderFirst.Height;
            for (int i = 0; i < bors.Count; i++)

            }

            borderFirst.Tag = Math.Round(h / borderFirst.Height) + "#" + Math.Round(w / borderFirst.Width);
            borderFirst.Width = w;
            borderFirst.Height = h;
