Sub collections

[arcanechimp]

Is there any way to use hierarchical data using this component?

What I mean is, every item in the table has a collection of sub items of a different type. I want to preserve the hierarchy in the table, so that the parent items have a row-span set to the size of the child collection, keeping the children grouped with the parent.

Example of what I am trying to achieve:

Thanks for all your work on this component - it is fantastic!

This is something I hadn't considered before, but I can definitely look into it.

My biggest concern right now is making sure it works well with the addExpandedRows plugin.

Hey @arcanechimp, did you manage to resolve this use case since our previous chat?

[arcanechimp]

Hi @bryanmylee, no, no luck yet.

I'm unsure where to begin. I tried playing around in the REPL with a small set of data back when I first posted, but could not figure out a way using the existing plugins to make it work.

I'll have another go and get back to you.

I'm currently quite busy with work but I'll try my best to help out!

It might take a lot of work to support this feature because right now Svelte Headless Table was built with the assumption that all row models are mapped 1-to-1 to table rows.

Yes, that was more or less what I discovered.

I guess it would have to be modeled using parent columns and child columns, along side the parents collection and child collections within them. I can see how ingrained the generic Item class is within the table and plugins, so introducing a new type may cause lots of headaches with the existing plugins.
