Description

There's currently no way to export data from the viewer. Adding a download button that exports the current page of results as CSV or JSON would be useful for quick data extraction without needing to write scripts against the Lance files directly.

Proposed approach:

  • Add an export button to the UI that downloads the currently displayed rows
  • Support CSV and JSON formats
  • Client-side generation from the already-fetched data (no backend changes needed)
  • Respect the current column filter selection
