Can you test this code below? Is this what you want to achieve?

@Component 
public class AllTableResponseConverter { 

 public AllTableResponse convert(Table table ) {
        
        List<AccountIdResponseConverter> convertedAccounts = new ArrayList<>();
        
        AllTableResponse allTableResponse = new AllTableResponse();
        allTableResponse.setId(table.getId());
        allTableResponse.setNumber(table.getNumber());
        for(Table t : table.getAccountList()) {
                AccountIdResponseConverter converter = new AccountIdResponseConverter();
                convertedAccounts.add(converter.convert(t));
        }       
        allTableResponse.setAccountList(convertedAccounts);
    
        return allTableResponse;
    }
}
