How to read table data when user clicks on a button in VBCS page

We have a requirement to allow users to cancel sales order lines in Fusion and other applications where the same order is imported into. Instead of logging into each and every application and cancelling sales order lines (which is time consuming), we wanted to build a custom VBCS page thru which user can cancel lines and VB page can automatically cancel those lines using OIC integrations.

To build the solution, we added a table component which is populated with sales order lines information. One additional column "Cancel Line?" is added with a Check Box to the table. This check box is enabled only when the current line status is "Awaiting Shipping".
