Executing %sqlcmd explore --table table --schema schema should display an HTML view of the table, users should be able to sort each column by clicking on the header and control the number of displayed items (e.g., 10, 20, 30) and move to the next set of images. Pretty much like this, except we won't include the search field in this iteration.

Interacting with the table (e.g., sorting a column) should trigger the execution of a SQL query, results should be fetched and the table must be updated. In other words, no processing should happen locally, everything should be computed in the SQL engine.

The feature should be complemented with a tutorial in the documentation. Most likely, the interactive component won't be visible from the tutorial so we should tell users to open it on Binder to see it in action.

There should also be detailed tests, although this is open for discussion since I'm unsure how we can simulate users clicking on the table.

Hmm why a new one? I kept the original open: #136
I guess the title is more explicit

The context got lost, I wanna make sure we are on the same page in terms of what to build: #146 (comment)

@edublancas please set the criteria we want here, here's what I'm assuming:

1. A working design of the feature.
2. Extensive tests
3. Document how to use it.
