我需要帮助将两个不同的行（具有相同的列）添加到同一数据表中

Question

在Windows窗体应用程序上工作，该应用程序从csv文件中读取数据并将数据添加到Datagridview。我遇到了一个问题，所有行都添加到了datable并显示在datagridview上。 datagridview显示前两个条件（如果有条件）和OneRow（仅条件）的数据行。如果datable和datagridview行填充有条件行OneRow，则它将不添加来自twoRow条件的行。但是我希望显示来自OneRow和TwoRow的行。当我在OneRow if条件中注释（/ ** /）时，TwoRow中的行也会填充datatable和datagridview。但是我都需要填充表格。预先感谢！

        Construct.MainDataTable.Columns.Add("Date", typeof(DateTime));
        Construct.MainDataTable.Columns.Add("Time");

        Construct.MainDataTable.Columns.Add("level");

        Construct.MainDataTable.Columns.Add(" Limit");
        Construct.MainDataTable.Columns.Add("last Limit");
        Construct.MainDataTable.Columns.Add("Data");
