Input Tables and filling some cells with predetermined values

I want to create a form with a fillable budget, using an input table. I want the user to be able to fill most detail of items and income but I would also like to be able to have some pre-determined values in the table.

For example, as you'll see in the attached excel sheet, in an income budget I want to be able to show Sales and sponorship as headings but then for the user to fill in items below that.

Is there a way of doing this with an input table? 

There is a way, but not with the Input Table, instead, you would need to use the Spreadsheet widget, which allows to set up calculation formulas: https://widgets.jotform.com/widget/spreadsheet

Please give it a try, and let us know if you need more help.

I know the spreadsheet widget, that’s not what i want to use though.

i want to use the table so I can make automatic calculations further on in the form, which spreadsheet doesn’t allow.

is there an alternative?

Unfortunately, the input table does not support the default content.
