我试图弄清楚如何向上移动一些 asp:xxx 控件的单元格（不是整行）。

下面是一个示例布局（使用文本），以显示数据的布局方式以及我希望它出现的内容。这一切都可以在页面加载后的代码中完成，因为条件将设置为显示或隐藏 2 行。

基本上，我需要（有条件地）隐藏单元格 XXX xxx YYY 和 yyy。并将它们向上移动。

一种选择可能是在您的代码中构建 DataTable，然后将其绑定到 GridView。向页面添加一个 GridView，类似于以下内容：

<form id="form1" runat="server">
    <asp:GridView runat="server" ID="ExampleGridView" 
                AutoGenerateColumns="true" ShowHeader="false" />
</form>

然后在页面加载中，您可以根据需要构建 DataTable，例如：

protected void Page_Load(object sender, EventArgs e)
{
    DataTable table = new DataTable();
    var condition = false;

    for (int i = 0; i < 4; i++) table.Columns.Add();

    AddArray(table, new string[4] { "AAA", "aaa", "AAA", "aaa" });
    AddArray(table, new string[4] { "BBB", "bbb", "BBB", "bbb" });
    if (condition)
    {
        AddArray(table, new string[4] { "CCC", "ccc", "CCC", "ccc" });
        AddArray(table, new string[4] { "DDD", "ddd", "DDD", "ddd" });
    }
    else
    {
        AddArray(table, new string[4] { "CCC", "ccc", "XXX", "xxx" });
        AddArray(table, new string[4] { "DDD", "ddd", "YYY", "yyy" });
        AddArray(table, new string[4] { "", "", "CCC", "ccc" });
        AddArray(table, new string[4] { "", "", "DDD", "ddd" });
    }
    ExampleGridView.DataSource = table;
    ExampleGridView.DataBind();
}

private void AddArray(DataTable table, string[] items) {
    var row = table.NewRow();
    row.ItemArray = items;
    table.Rows.Add(row);
}
