Naming convention for an out argument of type datatable

How can I have both prefixes “out” and “dt” in such an argument. Do you have a best practice? I cannot get Workflow Analyzer to stop complaining. Not a big issue but annoys me.
Currently I have it named as out_dt_UserTable and the analyzer shows me both the “prefix datatable arguments” and the “Arguments naming convention” warnings.

out_dtUserTable
out_UserTableDT

we do see often in the codes
