Show values of ragged columns in table view

[rly]

DynamicTable objects in NWB can contain ragged columns where each row has a different number of elements. This is represented as a VectorData object with an associated VectorIndex object in the same table that points to it (this index column almost always has the same name as the vectordata object plus a "_index" suffix. https://nwb-schema.readthedocs.io/en/stable/format_description.html#tables-and-ragged-arrays

The table view in Neurosift shows non-ragged column values, but not ragged column values or the column itself.

For example, this is a TimeIntervals table at path /intervals/test that has a custom ragged column that is not shown:

This is a Units table which has a "spike_times" column in the schema that is not shown:

It would be nice to show some of the values of each column, e.g., if the value is a 1D array: [value1, value2, ..., valueN]

In the table, the columns come from the colnames attribute of the dynamic table. In your example, does the VectorData column appear in the colnames?

In one example Units table I was looking at:
https://neurosift.app/?p=/nwb&url=https://api.dandiarchive.org/api/assets/2b9e441b-56bc-4be2-893e-0e02d22d239d/download/&dandisetId=000582&dandisetVersion=draft&tab=view:Units|/units

The spike_times does not occur in the colnames.

Should we somehow detect these additional columns? What should be the rule here?
