Question about summing a calculated column in History Table Card

Hello,

I am using the History Table Card in Home Assistant and I have a question about calculated columns.

I have several calc columns where one calculated column uses the result of other calculated columns.

For example:

* Without battery → calculated value
* With battery → calculated value
* Battery benefit → Without battery - With battery

The hourly values are displayed correctly in the table.

What I would like to do is sum the already calculated values of the Battery benefit column over a day.

In other words:

Hour 1 Battery benefit

* Hour 2 Battery benefit
* Hour 3 Battery benefit
* …
* Hour 24 Battery benefit
= Daily Battery benefit

I do not want to recreate the calculation outside the History Table Card. I want to use the values that the card has already calculated for the Battery benefit column.

I noticed that calc variables can be used by other calculations within the table, but I cannot find a way to use the calculated result of a column as a sum/total over the selected period.

Is there currently a way to do this?

For example, is there a syntax or configuration such as:

* sum: Batterybenefit
* stat_type: sum for a calculated column
* or another way to expose/sum the result of a calc variable?

If this is not currently possible, is there another recommended way to obtain the sum of a calculated column over the selected period?

The important point is that I want to sum the result of the existing calculation, not duplicate the underlying calculation in another sensor.

Thank you!
