I'm brand spanking new to the Web AppBuilder and am trying to develop a custom widget designed like the bottom half of the image shown below. I need a FeatureTable in the top 50% of the widget, and then a tab set with 3 tabs on the bottom half of the widget with a FeatureTable in each of the tabs.
I've been able to get the general UI design to appear in my custom widget, but I can't for the life of me get the FeatureTable objects to appear. I have populated the tables from their corresponding feature layers, as I've seen that data in the Chrome Developer Tools console window. I am able to get this set up and working with the Javascript API, but I'd obviously like to take advantage of all the free bells and whistles the Web AppBuilder provides.
