Styles for prime ng datatable

[gfellerph]

People are using this component in internal projects and we could provide styles for it: https://primeng.org/table.

### Tasks
- [ ] Add basic styles for the primeng table (colors, maybe paddings/margins)
- [ ] Add documentation page on how to install and use the styles

• Prime Ng Style generator could be an option
• Create our own?
• How final would this implementation be?
• Could create a standalone page and use iframes to display the component in storybook. But what about snapshots?
• Could we use angular-elements?
• Use the style creator and document with an image?
