This creates several usage examples for backend paging, filtering, sorting (single and multi) and a final example that ties it together with a graph.

Overall, these features look good. A few improvements came to mind:

  • Backend filtering shouldn't have to use the same query language as front-end. Users should be able to write their own backend DSLs. We could make this optional by providing a flag (filtering_validate_expression=False)
  • We should start thinking about row IDs soon. I'd like to tie these backend examples in with selected_rows so that I could filter my dataset, graph a few rows through a selection, then filter my dataset again, select another set of rows, and see those rows appended in my graph.
  • Filtering might be easier in the backend if the data was structured like [{'column': 'lifeExp', 'expression': '> 5'}]
  • However, we should keep in mind that we might add a richer filtering UI in the front-end with even more structure.
  • It's not clear to me what displayed_pages does.

I also intentionally left out the combination of "backend paging + front-end sorting" as I think that it just leads to confusion by the end-user. In other words, we should discourage this behaviour by leaving it undocumented.

Am I missing any functionality here?

Besides those remarks above, I don't think there is any other things to fill out for this section.

@cldougl - am I missing any examples here?

@Marc-Andre-Rivet @valentijnnieman - do these examples look right? Am I missing anything?

Next up (in a separate PR), I'll work on examples for:

  • Dropdowns (including updating dropdowns with backend paging)
  • Adding/Removing columns

I'm going to merge this as the target.
I'd still like feedback on these examples as they demonstrate the representative use of this component, and ultimately the documentation.

@chriddyp that sounds good to merge now then we can continue to work through

examples that represent of the level of customization that we need in
