for (int rowIndex = gridView.Rows.Count - 2; rowIndex >= 0; rowIndex--)
{
GridViewRow row = gridView.Rows[rowIndex];
GridViewRow previousRow = gridView.Rows[rowIndex + 1];

for (int i = 0; i < row.Cells.Count; i++)
{
if (row.Cells[i].Text == previousRow.Cells[i].Text)
{
row.Cells[i].RowSpan = previousRow.Cells[i].RowSpan < 2 ? 2 :
previousRow.Cells[i].RowSpan + 1;
previousRow.Cells[i].Visible = false;
}
}
}

GridView? Which one? Why do you think there is only one? Full type name, please.

There are a lot of good examples. For example:
- How to merge cells with equal values in a GridView[^]
- Rows and Columns Merging in ASP.NET GridView Control[^]
and so on...

ADDITION:
merge just 1st column (based on the code in first article)

C#

public static void MergeRows(GridView gridView)
    {
        for (int rowIndex = gridView.Rows.Count - 2; rowIndex >= 0; rowIndex--)
        {
            GridViewRow row = gridView.Rows[rowIndex];
            GridViewRow previousRow = gridView.Rows[rowIndex + 1];

            if (row.Cells[0].Text == previousRow.Cells[0].Text)
            {
                row.Cells[0].RowSpan = previousRow.Cells[0].RowSpan < 2 ? 2 : 
                                       previousRow.Cells[0].RowSpan + 1;
                previousRow.Cells[0].Visible = false;
            }
        }
    }
