What I'm trying to do is something complex, first what I have is a table that is being filled with 3 values each time I press a button, so what I want to achieve is that by pressing another button I can get all the data from the table
When I press add product takes an ingredient from the combobox rescues the value of the txtfield and the value of the last combobox, they are added to the table according to their classification. According to the image what I want to achieve is that by pressing the next button I can rescue all the values in the table and save them in the database I have.
