      2d-array of widths where the first dimension specifies columns and the second rows.

      For example, to layout the first two output blocks side-by-side on the top with the third
      block spanning the full width below, use `[[3,3], [1]]`.

      Use negative values to create margin. For example, to create space between the 
      output blocks in the top row of the previous example, use `[[3,-1, 3], [1]]`.
