Meta data in column name with Grafana + influxdb + Table panel

Hello.
I’m trying to show data from influxdb with table panel.
Everything is good except column name.
Column name contains some kind of meta like below

oldestTimestamp {_start="2021-08-20 06:27:52 +0000 UTC", _stop="2021-08-20 06:47:52 +0000 UTC", category="XXX", exchange="YYY", orderQty="ZZZ", pair="MMM-NNN", strategyName="SSS"}

Whenever data is updated, column name changes as start/stop time varies.
I need to use transform function of Grafana to arrange the order of column but it’s not applicable as column changes everytime.

I searched this forum and googled but couldn’t find any solution.

Hi @platoniclove

Can you share your panel JSON? Can you describe exactly how you’d like your table to appear?

Hi @mattabrams
Thank you for answering.
I want column names to be just simple as influxdb’s field name like “pnlPcnt” not "pnlPcnt {_start=“2021-8…}”.
I attached my json model below.

In your first screenshot, you are using a transform to rename one field. Does this not accomplish what you want if you rename the other fields?

@mattabrams
Transformation didn’t work as I expected.
I tried “Organize fields” function of transformation to rearrange the order of fileds.
It took field name with meta data like "pnlPcnt {_start=“20210820…” which varies by refreshing data. So it works for current data but it became useless as field name changes.

Below is a json model configuration of transformation.
