Hi,
So you want to store the data in a Custom table (so no direct page to navigate too).
Based on the logic you might want to have a look at the editingpage a custom table (just in Kentico itself), this page seems to support your case.
You can find code for this module in your Kentico Solution here:
/CMSModules/CustomTables/Tools/CustomTable_Data_List.aspx
