title: Ag-grid hiding rows
body: <p>Is there any implemented functionality to conditionally hide rows?</p>
  
  <p>I instantiate them like this:</p>
  
  <pre><code>let rows = [
      { name: "Adam", isVisible: true },
      { name: "Bert", isVisible: true },
      { name: "Carl", isVisible: false }
  ];
  
  for(let row of rows)
    row["height"] = row.isVisible ? 25 : 0;
  
  this.rowData = rows;
  </code></pre>
  
  <p>And then I provide this function to set the row height:</p>
  
  <pre><code>this.gridOptions.getRowHeight = (params) =&gt; {
      return params.data.height;
  }
  </code></pre>
  
  <p>This is not a perfect solution, especially because if the grid ends with a row of height 0 it shows that row anyway (with the height of 4px or so)</p>
