Hi @JabbarCRM,
There are many posts about how to sum the prices in the table if you want to add the sum into the table, you should initialize the output of Select action as an array variable:
1. I get these data from a SharePoint list instead of CDS, and initialize an array variable named Table. At the same time, I initialized an integer variable named Sum.

2. After that, create an Apply to each action to loop through all the items of the table, if the Price property is not null, use the increment variable action to increase the Sum variable:

3. After get the sum of price, create the following JSON and append to array variable. Then you can put the table variable into your email.
