What happened?

When using the sbb-table component and having one or more sticky columns configured, those columns get repainted in browser everytime the datasource gets updated, even if there is no change in the data. This behaviour causes problems in our project because animations beeing trigered when not wanted.

Here is a demo that simulates the problem we're having: https://stackblitz.com/edit/fslunt?file=src%2Fapp%2Fsticky-table-example.ts,src%2Fapp%2Fsticky-table-example.html

In this gif the repainting from the sticky columns is shown:

We would expect the repaintings from the sticky columns not to be happening and the animations not being triggered.

Is it possible to fix this behaviour?

Steps to reproduce the issue

1. Go to Demo: https://stackblitz.com/edit/fslunt?file=src%2Fapp%2Fsticky-table-example.ts,src%2Fapp%2Fsticky-table-example.html
2. Open webcontainer page in a new window
3. Open Chrome Developer Extension
4. Open Rendering tab (through 'More tools' in the menu from the extension)
5. The content being repainted is showed in green.
