Storybook: fix DataViews layout

[oandregal]

What?

The layout prop for the story didn't have the data defined in default layouts.

Why?

The styles defined in layout.styles wouldn't work.

Testing Instructions

npm install && npm run storybook:dev

Change the styles provided via defaultLayouts.table.layout.styles.description and verify that they are applied (max-width, etc. are inline styles of the table cell).
