Deleting rows with one specific empty column in DB

I am new to WIX, working on my first personal project with very limited knowledge of coding.
I am stuck in one step where my workflow requirement is to have a code to run on $w.onReady and to delete the whole row if one of my predefined field on code is empty, please see the example below as in second row Patient field is empty and this whole row 2 needs to be deleted on $w.onReady and I need help in compiling a code to achieve this.
