Function register_table 

pub fn register_table(
    context: &SessionContext,
    name: impl Into<String>,
    table: DeltaTable,
    options: ScanOptions,
) -> Result<TableRegistration, DeltaReaderError>

Registers one loaded Delta table in a DataFusion session.

Registration performs no scan. Existing registrations are preserved and reported through DeltaReaderError.

    &context,
    "orders",
    table,
    ScanOptions::default(),
)?;
