Create field in form based on added column in Tables

If i go to the TABLES view of an existing table and add (+ ADD) a new column how can I transpose it to the FORM view? It doesn't appear there.

The PDF Editor has the "Form Fields" we can choose from but the FORM Builder doesn't have that choice.

Please note that the column you add within the Tables page does not create a field on your online form.

If you wish for users to be able to fill out such field, then please create the field within the form builder. Your Tables page should then be able to display a column for that new field.
