您可以使用asp.net GridView控制来显示上述数据。

您需要做的就是对数据进行分组。您可以使用ado.net或Entity框架从数据库中获取数据。并将其与你的网格绑定。

HTML标记：

<asp:GridView ID="GridView1" HeaderStyle-BackColor="#3AC0F2" HeaderStyle-ForeColor="White"
    runat = "server" AutoGenerateColumns="false" OnDataBound="OnDataBound">
    <Columns>
        <asp:BoundField DataField="JobNo" HeaderText="Job number" ItemStyle-Width="150" />
        <asp:BoundField DataField="JobStage" HeaderText="Job stage" ItemStyle-Width="150" />
        <asp:BoundField DataField="JobStatus" HeaderText="Job status" ItemStyle-Width="150" />
    </Columns>
</asp:GridView>

代码背后：

  protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.IsPostBack)
        {
            DataTable dt = new DataTable();
            GridView1.DataSource = GetData("SELECT JobNo, JobStage, JobStatus FROM YourTABLE GROUP BY JobNo, JobStage, JobStatus");

            GridView1.DataBind();
        }
    }

private DataTable GetData(string query)
{
    DataTable dt = new DataTable();

    string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;

    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand(query))
        {
            using (SqlDataAdapter sda = new SqlDataAdapter())
            {
                cmd.CommandType = CommandType.Text;
                cmd.Connection = con;
                sda.SelectCommand = cmd;
                sda.Fill(dt);
            }
        }
        return dt;
    }
}

你必须在GridView的OnDataBound()事件中编写一些逻辑。在GridView填充记录后执行GridView的OnDataBound事件。反向循环在GridView Rows上执行，然后识别公共单元并将其合并到单个单元格中。

protected void OnDataBound(object sender, EventArgs e)
{
for (int i = GridView1.Rows.Count - 1; i > 0; i--)
{
    GridViewRow row = GridView1.Rows[i];
    GridViewRow previousRow = GridView1.Rows[i - 1];
    for (int j = 0; j < row.Cells.Count; j++)
    {
        if (row.Cells[j].Text == previousRow.Cells[j].Text)
        {
            if (previousRow.Cells[j].RowSpan == 0)
            {
                if (row.Cells[j].RowSpan == 0)
                {
                    previousRow.Cells[j].RowSpan += 2;
                }
                else
                {
                    previousRow.Cells[j].RowSpan = row.Cells[j].RowSpan + 1;
                }
                row.Cells[j].Visible = false;
            }
        }
    }
}
}

希望这会对你有所帮助。
