title: Creating a Filter Button in GridJS
body: <p>I am new to gridjs and am struggling to find a way to add filter buttons. I am looking to add dropdown selectors or buttons that will filter out entire rows if a specified value is not in a specified column.</p>
  <p>For example, if I have this table:
  |   Color  | Another header |
  | -------- | -------------- |
  | Blue     | Value1         |
  | Green    | Value2         |
  | Blue     | Value3</p>
  <p>Is it possible within gridjs to create a filter dropdown that if you select blue, it would filter out all non-blue values and vice versa if you selected green?</p>
