Hi,

DataGridView is difficult to achieve what you want.
There are some examples of using custom GridView on Github for your reference.

https://github.com/wsn931203/RowMergeView

Form1_Load:  
            this.rowMergeView1.Columns.Add("1", "Analyst");
            this.rowMergeView1.Columns.Add("2", "Date");
            this.rowMergeView1.Columns.Add("3", "Current");
            this.rowMergeView1.Columns.Add("4", "Previous");
            this.rowMergeView1.Columns.Add("5", "Current");
            this.rowMergeView1.Columns.Add("6", "Previous");
            this.rowMergeView1.Columns.Add("7", "Future");
            this.rowMergeView1.Rows.Add("1", "2", "3", "4", "5", "6", "7");
            this.rowMergeView1.ColumnHeadersHeight = 40;
            this.rowMergeView1.ColumnHeadersHeightSizeMode = DataGridViewColumnHeadersHeightSizeMode.DisableResizing;
            
            this.rowMergeView1.AddSpanHeader(2, 2, "Price Target");
            this.rowMergeView1.AddSpanHeader(4, 3, "Rating");

            for (int i = 0; i < this.rowMergeView1.Columns.Count; i++)
            {
                this.rowMergeView1.Columns[i].SortMode = DataGridViewColumnSortMode.NotSortable;
            }

Best regards,
