Match values from different columns to delete javascript, mocha

I have a data table as so

*  c1  c2       c3
r1 a  1.2  deletebtn
r2 b  1.4  deletebtn
r3 a  2.3  deletebtn
r4 b  1.2  deletebtn

I am trying to delete entry in the test that will satisfy parameters I pass into function. e.g. deleteItem(a,2.3). I am able to delete searching by only c1, using find by xPath and checking if contains 'a', then delete it. How would I go about matching data that are in different columns, before calling .click() on the delete button? Im not looking for code, just the logic that I would write the code around. Thanks.
