How to make user generated table?

Hello Guys,
I’am required to get user inputs from the user like we do on a form and generate a table based on the screen shot. I’m not sure how to have the data know which strand it belongs to .

Each column with a blue background header is a strand like Student Particulars, Number Concept etc.
Each strand contains sub-topics like Student Particulars has UEN, Name of Student, Class and Section.
Each of the sub-topics contains respective data. like UEN-000001, Student-1,Class, Section.

Now i need the user to define each strand and its sub topics and also he should be able to add data thought the form.

I’m kind of lost here… need help.
Needs to be done on React.
