Hey @linuswzg!
As @ScottR mentioned, you can use the built in Get tags on a file from s3 action type to retrieve the tags and then display them as a caption in the table. I set this up, only one of my objects has a custom tag, but the method should be the same regardless!
Create a JS query to run through the list of objects to trigger the query to get tags (for me, I iterated through another table's data set):
The S3 resource action that grabs the tag for each object:
Format the returned values into an array that the table can use:
Set the caption on the table column you want it to appear on:
Let me know if you have any issues with that!
