No indication that table is being filtered

[keyserj]

Describe the bug
When I add a filter, if I hide it, there's no indication of the table being filtered:

If I'm working with a filter for a while, this can be annoying, but it'll get worse if we persist filters, because I'll forget if I was using one. I could leave the filter showing the whole time, but if I'm filtering many nodes, the filter takes up a lot of the screen, and that's annoying too.

To Reproduce
Steps to reproduce the behavior:

See video above

Expected behavior
Ideally, there'd be a little icon or something to show if there's filtering happening. The table library we're using actually does have this:

but we're disabling it because it would awkwardly outside of the node in the cell.

Additional context

Technical ideas

• maybe we could remove the node box from the cell, putting all the node data directly in the cell
• maybe we could use a different icon for the filter in the table toolbar, if the filter is hidden but there's a filter being used

made it clear how to find if it's filtering in #325
potentially could add more indication but it doesn't seem like as big of a deal as it was
