title: Set position of Angular Material Tooltip
body: <p>I am using mat-table to display records in Grid and using matTooltip to display the tooltip on mousehover.<br>
  I want to display the tooltip near mouse pointer or at starting position of the row. </p>
  
  <p>But in my case, Tooltip always displays at the center of the row. I tried set position in css but no luck. </p>
  
  <p>Can someone please help on this.</p>
  
  <p><strong>HTML:</strong></p>
  
  <pre><code>&lt;mat-row
    *matRowDef="let row; columns: mGridColumns;"
    (click)="onRowClick(mGridDataSource, row)"
    [matTooltip]="row.tooltipText" [matTooltipClass]="'row-tooltip'"&gt;
  &lt;/mat-row&gt;
  </code></pre>
  
  <p><strong>CSS:</strong></p>
  
  <pre><code>.row-tooltip {
        position: relative !important; 
        right: 30px !important;
        background-color: #fafafa; 
        font-size: 12px; 
  }
  </code></pre>
