I have two custom array types - `TSeries <: AbstractVector` and `MVTSeries <: AbstractMatrix` in package TimeSeriesEcon - that don’t display correctly in the Julia Workspace in VS Code. The table viewer is shows the numbers correctly, but the column names and row dates are not shown, just 1-based indexes.

How can I customize these displays for my types? I’m not able to find any information about the protocols the VSCode Julia extension uses this. Is there some method I need to define for my types?

Column names are currently hard-coded as `1:N` for all `<:AbstractMatrix`es. For other tables we’re looking at `propertynames` or `fieldnames` instead, which I assume would also work for you?
