Spreadsheet view

[cordasfilip]

Have you thought about adding a spreadsheet view to this? Something like excel on steroids there is a good spreadsheet control for blazor https://github.com/anmcgrath/BlazorDatasheet that could be integrated. that could be useful. Might require autoupdates. This just something to think about.

Thanks for the suggestion! This is a great use case for Verso's extension system.

Rather than adding a built-in spreadsheet view, the recommended approach would be to build this as an IDataFormatter extension. You'd create a formatter that targets IEnumerable<T> (or whatever types you want the grid for) and returns a CellOutput("text/html", ...) with your spreadsheet rendering. The formatter gets picked up automatically for any matching return type in a code cell.

You can load custom extensions into a notebook via #!extension from either a NuGet package or a local DLL:

#!extension MySpreadsheetFormatter 1.0.0

or

#!extension ./path/to/MySpreadsheetFormatter.dll

This keeps the core lightweight while letting you bring in whatever grid control fits your needs. The IDataFormatter interface gives you SupportedTypes, Priority, and CanFormat to control exactly when your formatter activates. If you want to prototype something quickly without building a full extension, you can also return styled HTML directly from a code cell by constructing a CellOutput("text/html", htmlString) with your table markup.
