So can you post your (complete) incoming data, the flow you currently have and a screen capture of the dashboard as it currently is?

I appreciate that this is a commercial system, you might need to falsify the data to an extent

I am attaching the SS of flow, dashboard as it currently, flow and debug panel...

To address just the rounding issue for your table, not whether your code is the best style, nor the issue of whitespace for Agg2, the function which constructs the table can be tweeked like this:

ps this is rounded to the _nearest_ 0.01 not rounded _up_ to 2dp. Do you really need to round up?  
I think Math.ceil() rounds up. Not sure how it works with the negative numbers though.

pps Do you see the same missing values on the Agg2 line? This might be a problem in my setup.

Thank you so much for your king help!  
Edit  
It's working in my case.

I have seen that missing value. It's problem in my set up. I am trying to find out it.
