need to implement a datagrid like an excel sheet (ie Handsontable)

I need an excel-like data grid on my current webpage (internal website) that allows me to enter item SKU Details of a Sales Order. Please see attachment. Currently, we are entering this information through simple CRUD inline form with ADD/EDIT/DELETE/UPDATE buttons. Even though this app is using classic ASP. The code here can be written in PHP if required. The code should use AJAX/Javascript/Handsontable to save data in a table in MS Access database. So this will be an ODBC 32-bit connection. Its a simple 1 page , 1 single table. I am flexible with other choices. Not restricted to Handsontable. Please let me know your preference and why. I don't presume this to take longer than 1 hour for anyone familiar with this. I have an existing internal website that I am trying to upgrade with patchwork. If successful, other work may follow.
