Address the points related to this from this issue #3095 or anything else that is not covered.

Points related to issue #3095 will be addressed separately.

What is the reasoning? That doesn't make sense to me because this PR is adding support for the table view in traces and it is incomplete knowing something is not working. You could address it separately for other panel types.

Please check this with the formula. I suspect it will break because the formula needs a join key. One way I workaround this in metrics is by adding now() for the timestamp so the ts is there for the sake of JOIN and still produces the correct result.

Those changes are not related to table view changes. The issue existed previously in the function common for time-series and table view.

If it was mentioned that the issue exists within the reader.go then it would have been easier to see why it made sense to think about addressing separately. Otherwise, it's not clear where the issue exists and why it should be addressed separately.

Addressed with now() as ts.
