Sum up of Table

I wanted to get the sum of calculated sum in my table.

So I was creating a table in kintone and per row there is the calculated value.

And I want to have a sum of all the calculated value in each row on below of my app.  Like below:

I already have the table, they just need to click + sign to add rows. 

Can someone help me to do this on my app?

Thank you.

SUM function can allow you to add values(numbers or dates) in a table using a calculated or text field but the calculated or text field will be outside the table, not inside the table in an app as you can see in the following link.

In this case, for “Values” to sum up, please specify the code of a “Number” field, the formula that results in a numerical value, or a number.

 

For example, to sum up values in the Subtotal fields, whose field codes are “AMT_C” of a table, the formula in a calculated or text field is SUM(AMT_C).
