I was trying to show/hide columns of a table based on logical criteria. The forum has answers to this question but they rely on using the "Dynamically show keys" option in the column details panel. However, the column settings don't show the "Dynamically show key" option anymore:
I can have the user show/hide columns via the nifty multiselect hack [Youtube: Tappers Tips #2] but it seems the wrong approach here. What I really want to do is to programmatically change the visibility of the columns based on true/false conditions. Any ideas?
