Dynamically add a column to react table on button click

I am trying to add a column to the react table using an add column button, but I am a little confused on how to implement this. I want to be able to add a column to the corresponding side that the button is clicked. Do I need to create a custom function and add it to my columns array or is there an easier way to implement this?

Here is the code.

/* eslint-disable react/jsx-props-no-spreading */

    td {
      margin: 0;
      padding: 0.5rem;
      border-bottom: 1px solid black;
      border-right: 1px solid black;

      :last-child {
        border-right: 0;
      }
    }
  }
