Depending on the checked status of a field named - toggle_valuation_rate - in the parent table Sales Invoice, we need to toggle an entire column named - Valuation Rate (Data field that fetches item_code.valuation_rate) - in the child table - Sales Invoice Item.

Please suggest.

You should use jquery to hide it, there is no built in method for this, at least not that i know.
