推荐答案

有很多很好的例子。例如：

- 如何在GridView中合并具有相等值的单元格 [ ^ ]

- ASP.NET GridView控件中的行和列合并 [ ^ ]

和所以...



附加：

合并第一栏（基于第一篇文章中的代码）

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)

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;
            }
        }
    }
