title: Filtering different columns in a material table
body: <p>I am trying to add different filters to a material table. To be more precise I am trying to reproduce something similar to the following GIF</p>

  <p>For doing so I am following irowbin's response in the following <a href="https://github.com/angular/material2/issues/6178" rel="noreferrer">Github thread</a> but I can't really produce what I want based on his guidelines</p>
  
  <p>Is there any working example on Stackblitz or Github so I can follow and create multiple search filters inside mattable?</p>
