Extend saved views to support column display & ordering

[dlhck]

Currently saved views only support filters. Should also allow:

• Selecting which columns to display
• Defining column order

This would complete the saved views feature for data tables.

Hey @dlhck, can I work on this issue?

[dlhck]

@PavanendraBaahubali of course! You don't have to ask for permission at all - just get started & open up a PR when finished! 💯

Hey @dlhck, I’ve raised PR #3988. I’ve made the changes after the CodeRabbit review—could you take a look and let me know if everything looks good?
