ClosedXML report - format of input list

Question

The format for sending data to a closedXML template is a bit confusing to me.

In the Flat tables docs there's a sample for a template with header info and data from a list for the report, but I don't see where the list is connected to the template.

I have a similar scenario - header info for the top, data in a list for the report.

I've tried defining an object with all the data in it:

public class AllocationExportData
{
    public List<AllocationExportItem> AllocationList { get; set; }
    public string Host_custname { get; set; }
    public string Host_custaddr { get; set; }

}

and setting up the template using those variables

But only the top two values are being found

I figure I'm naming something wrong, or setting up the object wrong.

Anyone?
