Description

When the summary isn't available for an article and it is loading:

  • Remove the headers from the table
  • Add an empty cell that fils the screen
  • Add a label to the center of the cell that says "loading…"

(We may come back to add a proper loading animation, but this is sufficient for beta purposes)
