How can I a Salesforce lookup field to a skuid page table as a reference/lookup field and not a read

I am creating a quick page to add contacts to accounts. However, I am trying to add account name field as a lookup field - but the only option that adds to the table is a string. 


The account would need to be a REFERENCE field in order to get the lookup dialog option.  

Are you using Account__c (REFERENCE) or Account__r.Name (TEXT)?
