Hi TaylorPA,
Based on your description, you wonder to change the column width of Summary View. Could you tell me where did you wonder to change the column width? I test it in my own environment, and I cannot change the width of Summary View in website.
As shown in the following figure, I can edit the Summary View and change the column width manually by the two-head arrow icon in Access 2013 local client.
If my understanding incorrect, I suggest you post a shortcut so that I can help you solve this issue more precisely. Im glad to help and follow up your reply.
Hope its helpful.
