Hi Tess,
New Retool user here.
I have the same issue with the new table component.
I have a mapped field that has a integer data value that is mapped to a table for the data display.
the filter action on that column only filters the value and not the display.
Hi @Shegs,
I'm able to reproduce this too 
Thanks for flagging! I am reaching out to our team internally
Hey @Tess,
To toss my hat in the ring as well, I am still seeing this behavior as well on the new table version.
Added your +1!
Same issue here.
Thanks.
Hi there! Unfortunately, I don't have an eta for this one I'll let the team know you've checked in
Thanks @Tess, this is one of those things that as we have our data system normalized actually impacts a lot of our workflow with the filtering. Let me know if this is something that plans on being addressed.
This makes it very difficult. Are there any workarounds?
No update yet, unfortunately It is in our queue to be fixed, but it's hard to say what the timeline will be. I'll add this feedback to the internal ticket!
@Tess Just following up to see if there has been any traction. I can see that it has been a bug for a while. Any news or way to escalate this a little bit?
+1
I would like to filter by mapped values.
