您可以使用网格视图的 Row_Created 事件。您可以在其中设置 Grid 视图的 ColSpan 和 Row Span 属性

请参阅以下示例代码：

protected void grvMergeHeader_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        GridView HeaderGrid = (GridView)sender;
        GridViewRow HeaderGridRow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);
        TableCell HeaderCell = new TableCell();
        HeaderCell.Text = "Employee Information";
        HeaderCell.ColumnSpan = 3;
        HeaderGridRow.Cells.Add(HeaderCell);

        HeaderCell = new TableCell();
        HeaderCell.Text = "Joining Date";
        HeaderCell.ColumnSpan = 2;
        HeaderGridRow.Cells.Add(HeaderCell);

        grvMergeHeader.Controls[0].Controls.AddAt(0, HeaderGridRow);

    }
}
