Trying to figure out a way of getting the expandable section below the main row - expand to be full width of the table. I am having issues with it just fitting within the first column. Are there alternatives? First I wanted to make a slide in Panel once you click a link … that didn't work. Then I tried a panel with a toggle... that didn't work. Any and all help will be appreciated.
