Yes, I tried that but the Excel Exporter throws an error stating a key isn't found. I assume it is still trying to use the Band[1] column keys during export.
I am going to try this to see if I can get around it.
private void OnInitializeRowDataExcelExporter(object sender, ExcelExportInitializeRowEventArgs e)
{
e.SkipDescendants = SkipChildBandExcelExport;
}
