Hi Nicholas L.,
Could you please provide more information about the outcome, what exactly is not working correctly?
I created a simple testpage with a table of 8 columns. “Allow users to show/hide columns” is enabled for each column. Columns 1 - 4 are shown by default, columns 5 - 8 are not. Could you please create a new page in your org using the XML below? Please let me know if that page works fine. If not, which Skuid version is currently installed? If it works as you expect, please compare your table settings to mine and let me know if you could find a significant difference. I used a UI-only model so that you can easily test it in your org:
