For now, there's no option to add a column for payment date. However, you can still see when an invoice was paid by looking at the Invoices and Received Payments report. 

The date to the left of the payment transaction is technically the date of the payment. Then, the transaction below it is the invoice the payment was attached to. 

I totally agree that being able to add a Payment Date column would help you determine when it was paid.

Having said that, I would recommend sending feedback about this to product engineers. Feature requests and customer suggestions are reviewed when new updates are designed.  Please go to this article for more details: How Do I Submit Feedback?
