Class ExcelRequiredAttribute
Marks a property whose column must be present in the header row; parsing throws when the header is read if no matching name is found. By default every data row's cell must also be non-empty (and must parse successfully — a non-empty but unparsable cell fails the same way as a blank one), throwing on the first row that fails either check. Set AllowEmpty to true to require only the column's presence. Contrast with ThrowOnParseFailure, which governs parse-failure behavior only for non-required columns.

AllowEmpty
When true, only the column's presence in the header is required; individual rows may leave the cell blank or unparsable without throwing. Defaults to false.
