Fill Html Table and pass the data to the database

Hello 

I need to create a form with several controls such as textbox and DateTime then by entering data and press add button, I need to add several records , the data will be added to l Html table, at the end, if I press submit, It will pass the data to the database (Controller).  I need to perform CRUD on HTML table before passing its values to the controller. 

I tried with 

http://www.c-sharpcorner.com/article/pass-dynamically-added-html-table-records-list-to-controller/ 

but it is not working 

I have seen that in waveapps.com as an example. 

any IDEA? 

Thanks
